fix(sdk): keep subgraph status complete when values arrives late (#2482)
## Summary - Fix `SubgraphDiscovery` so late host-namespace `values` snapshots do not reset subgraph status from `complete`/`error` back to `running`. - Root cause: the SDK’s content pump (`values`) and lifecycle watcher (`lifecycle`) are separate streams; `onEvent` can deliver a final `values` event after terminal `lifecycle`, which left some nodes stuck as “running” in `useStream` subgraph UIs (e.g. graph-execution-cards). - Add regression tests for completed and failed subgraphs receiving a late `values` event. |

fix(sdk): normalize HITL edit decisions for Python servers (#2469)
## Summary - Normalize HITL resume payloads in `StreamController.respond()` and `respondAll()` so edit decisions include both `editedAction` and `edited_action`. - Add `normalizeHitlResponseForServer` in the SDK UI layer and export it for direct use. - Cover normalization with unit tests on the payload helper and on `respond()` wiring. |

fix(sdk): route headless tool resumes through respond on v1 stream (#2467)
## Summary
- Fix headless-tool resume on the v1 stream protocol by routing resume
payloads through `applyHeadlessToolResumeCommand` (`respond` /
`respondAll`) instead of `submit(null, { command })`.
- Export `applyHeadlessToolResumeCommand` and
`HeadlessToolResumeController` from `@langchain/langgraph-sdk` and
re-export from `@langchain/react`.
- Strengthen headless-tool browser tests across React, Vue, Angular, and
Svelte to assert tool result values, final agent message, idle loading
state, and no lingering interrupts.

fix(langgraph-checkpoint-mongodb): include pendingWrites in list() results (#2260)
## Summary Fixes #2205 Fixes #589 `MongoDBSaver.list()` does not query or return `pendingWrites` in the yielded `CheckpointTuple` objects. This is inconsistent with `getTuple()` (which correctly queries the writes collection) and with other checkpointer implementations like Postgres. ## Fix Added the same `pendingWrites` query from `getTuple()` into `list()`, ensuring each yielded checkpoint tuple includes its pending writes. ## Test Plan - Store checkpoints with pending writes via MongoDBSaver - Call `list()` and verify `pendingWrites` are populated - Compare with `getTuple()` output to confirm consistency 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Co-authored-by: Claude Opus 4.6 (1M context) <noreply@anthropic.com> Co-authored-by: Christian Bromann <git@bromann.dev> Co-authored-by: Cursor <cursoragent@cursor.com> |

fix(core): prevent Zod schema defaults from overwriting checkpoint state in Command.update (#2035)
Fixes #2031 When using `Command({ update })` with a Zod schema that has `.default()` on fields, Zod's `parse()` injects default values for missing fields into the update object. These injected keys then overwrite values restored from the checkpoint. **Root cause:** `_validateInput` passes `Command.update` through `interopParse(schema, input.update)`, which triggers Zod defaults for any field not present in the update. **Fix:** After parsing, filter the result to only include keys that were present in the original update input — matching the behavior of `StateSchema.validateInput` which already iterates only over `Object.entries(data)`. Added regression tests for both Zod v3 and v4. --------- Co-authored-by: Christian Bromann <git@bromann.dev> |

fix(langgraph-checkpoint-mongodb): MongoDB checkpointer metadata filter (#2186)
## Summary
- The `list()` method's metadata filter queried `metadata.${key}`
against a serialized binary blob, making it silently nonfunctional (dead
code)
- Added a plain JSON `metadata_search` field alongside the serialized
`metadata` in `put()`, and updated `list()` to query against it
- This is consistent with how Postgres (native JSONB `@>`) and SQLite
(`jsonb(CAST(...))`) handle metadata filtering
## Test plan
- [x] Existing unit tests pass (6/6)
- [ ] Integration test with real MongoDB to verify filter works against
`metadata_search`
Fixes #1591

fix: preserve non-plain Send args (#2409)
## Summary - preserve non-plain object instances while deserializing `Send`/`Command` argument trees - keep recursive reconstruction for arrays, plain object records, serialized `Command`, and serialized `Send` payloads - add a regression test covering `Set`, `Map`, `Date`, and a custom class instance passed through `Send` Fixes part of #1142. ## Test plan - `pnpm install --frozen-lockfile` - `pnpm --filter @langchain/langgraph exec vitest run src/tests/constants.test.ts --testNamePattern "preserves non-plain objects"` - `pnpm --filter @langchain/langgraph exec vitest run src/tests/constants.test.ts` - `pnpm exec oxfmt --check libs/langgraph-core/src/constants.ts libs/langgraph-core/src/tests/constants.test.ts` - `pnpm exec oxlint libs/langgraph-core/src/constants.ts libs/langgraph-core/src/tests/constants.test.ts` - `git diff --check` - `pnpm --filter @langchain/langgraph build` --------- Co-authored-by: Christian Bromann <git@bromann.dev> |

fix(langgraph): pass context with stateful RemoteGraph runs (#2457)
## Summary - Fix [#1922](https://github.com/langchain-ai/langgraphjs/issues/1922) by porting the Python [langgraph#6497](https://github.com/langchain-ai/langgraph/pull/6497) behavior: `RemoteGraph` pops `thread_id` from `config.configurable` (it stays in the URL path) and passes `context` as a top-level field to `client.runs.stream()`. - Stateful remote runs can now combine checkpointing (`thread_id`) with `context` for middleware / `contextSchema` without the server rejecting ambiguous parameters. fixes #1922 |

fix(sdk): prefer completed task's direct mapping over pending checkpoint's positional guess in fetchSubagentHistory (#2455)
Fixes #2454 ## Problem `StreamManager.fetchSubagentHistory` (`libs/sdk/src/ui/manager.ts`) restores each subagent's conversation from its subgraph checkpoint by first resolving every subagent `tool_call_id` to its subgraph `checkpoint_ns`. It scans the parent thread's history **newest-first** and, per checkpoint, tries two strategies: 1. **Direct mapping** — read the `tool_call_id` straight off a completed PUSH task's result `ToolMessage` (`task.name + ":" + task.id`). The code comments correctly call this *"more robust than positional alignment ... preferred"*. 2. **Positional fallback** — when task results aren't populated yet, align push tasks to the AI message's subagent tool calls by Send index (`task.path[1]`). The loop **breaks on the first checkpoint that yields any mapping** (direct *or* positional). That break is the bug. When the most recent checkpoint is a still-pending PUSH task — e.g. a run stopped at an interrupt — its task has no result, so the direct map is empty and the **positional fallback runs against the head checkpoint instead**. The fallback's backward scan of `values.messages` then latches onto a *stale* AI message whose subagent actually **completed in an older checkpoint**, positionally aligns it to the head's unrelated pending task, and breaks — before the loop ever reaches the older checkpoint whose task result holds the **correct** direct mapping. Net effect: the subagent's history is reconstructed from the **wrong subgraph namespace** (or not at all). A newer, lower-confidence positional guess silently shadows an older, authoritative direct mapping — the opposite of the code's stated intent. ## Fix Split namespace resolution into two phases: 1. **Phase 1 — direct mapping across the _entire_ history first.** Collect all `tool_call_id → namespace` mappings from completed task results before attempting any fallback. These are unambiguous, so no pending head checkpoint can pre-empt them. 2. **Phase 2 — positional fallback only for tool calls still unmapped** after phase 1 (the genuinely live/pending case). This preserves the existing behavior for in-flight runs while guaranteeing a correct direct mapping is never overwritten by a positional guess. No backend/protocol change is required — the server already serializes the correct material (the completed task result with the matching `tool_call_id`); only the client-side resolution order was wrong. ## Testing - Added a regression test (`fetchSubagentHistory namespace resolution`): a pending head checkpoint sitting in front of an older checkpoint that holds the correct completed mapping. Verified it **fails on the pre-fix code** (`expected [ 'Stale pending result' ] to include 'Correct research result'`) and **passes with this change**. - `vitest run` (SDK): **595 passed**, no type errors. - `oxlint`: 0 warnings / 0 errors · `oxfmt --check`: clean · `tsc -p libs/sdk/tsconfig.json --noEmit`: clean. --------- Co-authored-by: Claude Opus 4.8 <noreply@anthropic.com> Co-authored-by: Christian Bromann <git@bromann.dev> |

fix(langgraph): decouple ContextType from configurable in PregelOptions (#2037)
## Summary
When a `StateGraph` is created with a `contextSchema` (Zod), two
TypeScript errors occur:
1. **TS2589** ("excessively deep type instantiation") on the
`StateGraph` constructor
2. **TS2322** on `invoke()`/`stream()` - context schema fields (e.g.
`userName`, `userId`) are incorrectly required inside `configurable`
instead of top-level `context`
**Root cause:** `PregelOptions` extends `RunnableConfig<ContextType>`,
which maps the context type onto `configurable?` at the invoke/stream
level. The deep generic chain `StateGraph → Pregel → PregelOptions →
RunnableConfig<ContextType>` causes TS2589 with complex context schemas.
And TS2322 forces users to put context fields in `configurable` instead
of top-level `context`.
**Fix:** Remove the `<ContextType>` generic parameter from
`RunnableConfig` in `PregelOptions` only. This breaks the deep generic
chain at the invoke/stream boundary while preserving typed
`configurable` and `context` inside node callbacks (via
`LangGraphRunnableConfig<T>` / `Runtime<T>`).
## Changes
- **`libs/langgraph-core/src/pregel/types.ts`** - `PregelOptions` now
extends `RunnableConfig` (default) instead of
`RunnableConfig<ContextType>`. This is the only production code change.
- **`libs/langgraph-core/src/pregel/runnable_types.ts`** - Restored
`Runtime.configurable` to `ContextType` and `LangGraphRunnableConfig` to
extend `RunnableConfig<ContextType>` (reverting a previous attempt that
broke backward compat).
- **`libs/langgraph-core/src/tests/pregel.test-d.ts`** - Removed two
`@ts-expect-error` directives for invoke-level configurable (now
`Record<string, any>`, validated at runtime by Zod).
- **`libs/langgraph-core/src/tests/issue_10270_repro.test-d.ts`** -
Regression test reproducing both bugs from the issue.
## Trade-off
| Aspect | Before | After |
|--------|--------|-------|
| `graph.invoke({}, { configurable: { bad: 123 } })` | Compile error |
Compiles, validated at runtime |
| `graph.invoke({}, { context: { ... } })` | Compile error (TS2322) |
Compiles correctly ✓ |
| Node callback `config.configurable` / `config.context` | Typed as `T`
| Typed as `T` (unchanged) ✓ |
| `new StateGraph({ state, context: zodSchema })` | TS2589 | Compiles ✓
|
The only loss is compile-time validation of `configurable` content at
invoke level - mitigated by runtime Zod schema validation which the
codebase already performs.

chore: version packages (#2445)
This PR was opened by the [Changesets release](https://github.com/changesets/action) GitHub action. When you're ready to do a release, you can merge this and the packages will be published to npm automatically. If you're not ready to do a release yet, that's fine, whenever you add more changesets to main, this PR will be updated. # Releases ## @langchain/langgraph-checkpoint@1.0.3 ### Patch Changes - [#2352](https://github.com/langchain-ai/langgraphjs/pull/2352) [`14f2a79`](https://github.com/langchain-ai/langgraphjs/commit/14f2a796912e81d7f52f0a4f16747f6d0a269209) Thanks [@Nagendhra-web](https://github.com/Nagendhra-web)! - fix(langgraph-checkpoint): block prototype pollution in MemorySaver via reserved storage keys `MemorySaver` previously embedded `thread_id`, `checkpoint_ns`, `checkpoint_id`, and `task_id` directly into property accesses on the nested plain objects `this.storage` and `this.writes`. A caller able to shape any of those fields (every quickstart, tutorial, and test fixture uses `MemorySaver` by default) could pass `"__proto__"`, `"constructor"`, or `"prototype"` and have the subsequent assignment mutate `Object.prototype`. From that point every plain object in the process inherits the injected property, breaking `for...in` loops, truthy short-circuits, and downstream serializers across unrelated code paths. CWE-1321. Adds an `assertSafeStorageKey` chokepoint applied at every public entry that touches `storage` or `writes` (`put`, `putWrites`, `deleteThread`, `getTuple`, `list`). The guard rejects non-string values, the empty string (unless explicitly opted-in for `checkpoint_ns`), and the three prototype-pollution keys. Behaviour for valid string identifiers is unchanged. ## @langchain/langgraph-checkpoint-redis@1.0.6 ### Patch Changes - [#2350](https://github.com/langchain-ai/langgraphjs/pull/2350) [`1e73c6b`](https://github.com/langchain-ai/langgraphjs/commit/1e73c6b4630bbc4aa976eea4bfc33c4f753b7ee9) Thanks [@Nagendhra-web](https://github.com/Nagendhra-web)! - fix(checkpoint-redis): block Redis KEYS / SCAN pattern injection via top-level identifiers `RedisSaver` and `ShallowRedisSaver` previously embedded `thread_id`, `checkpoint_ns`, `checkpoint_id`, and `task_id` directly into Redis keys and `client.keys(pattern)` calls with no validation. A caller able to shape any of those fields (multi-tenant SDK deployments where the `RunnableConfig` originates from request input, or webhook payloads that flow into a persisted thread) could promote a string identifier into a glob pattern (`*`, `?`, `[...]`) or escape character (`\`). The most severe sink is `deleteThread`: a `threadId` of `*` issues `client.keys("checkpoint:*:*")` followed by `client.del(...)`, deleting every checkpoint in the database across every tenant. `getTuple`, `list`, and `loadPendingWrites` are exposed to the same pattern via the fallback paths that bypass the existing `escapeRediSearchTagValue` defense. Adds a single `assertSafeKeyComponent` helper exported from `./utils.js` and applies it at every key-building site. The guard asserts the value is a non-empty string (the empty `checkpoint_ns` default is opt-in via `{ allowEmpty: true }`) and rejects the Redis pattern meta-characters `* ? [ ] \`. The `:` delimiter is intentionally permitted because LangGraph emits it as a legitimate part of `checkpoint_ns` for subgraphs / nested graphs, where it only ever appears as a literal in the key. Behavior for valid string identifiers is unchanged. ## @langchain/langgraph-api@1.2.3 ### Patch Changes - [#2447](https://github.com/langchain-ai/langgraphjs/pull/2447) [`80c2806`](https://github.com/langchain-ai/langgraphjs/commit/80c2806cb2da93745a640664bd0cf603c2361da9) Thanks [@christian-bromann](https://github.com/christian-bromann)! - protocol-v2: fold forkFrom client-side and honor per-run multitaskStrategy The SDK now folds the ergonomic `forkFrom` option into `config.configurable.checkpoint_id` before sending `run.start`, so the agent server only ever accepts the single, legacy-compliant fork field (`forkFrom` no longer hits the wire). The protocol-v2 reference servers drop their top-level `forkFrom` normalization accordingly.

fix(sdk): add back respondAll and respond config/metadata (#2448)
## Summary
- Add `respondAll(responsesById, options)` to the stream controller and
the React/Angular/Svelte/Vue wrappers, resuming multiple interrupts
pending at the same checkpoint in a single `Command({ resume })`. This
is required for runs that pause on several interrupts at once (e.g.
parallel tool-authorization prompts), which sequential `respond()` calls
cannot service.
- Change `respond()` to take an options object (`{ interruptId?,
namespace?, config?, metadata? }`), folding run-level
`config`/`metadata` onto the resumed run so it applies the same
configurable values and metadata a fresh `submit()` would.
- Extend `ThreadStream.respondInput()` to accept a `responses` batch
(mutually exclusive with the single `interrupt_id`/`response`) and clear
all responded interrupts from local state.
- Update the protocol-v2 reference servers (`embed/protocol.mts`,
`protocol/service.mts`) to read the `responses` batch plus
`config`/`metadata` leniently and fold them onto the run servicing
`input.respond`.
- Update docs (interrupts/use-stream) across all framework packages and
add controller tests for batched resume.

fix(langgraph-checkpoint): block prototype pollution in MemorySaver via reserved storage keys (#2352)
## Summary Closes a prototype-pollution sink (CWE-1321) in `MemorySaver`. A caller able to shape `thread_id`, `checkpoint_ns`, `checkpoint_id`, or `task_id` (every quickstart, tutorial, and test fixture uses `MemorySaver` by default) can pass `\"__proto__\"`, `\"constructor\"`, or `\"prototype\"` and have the subsequent property assignment mutate `Object.prototype`. The audit posted in #2346 (cc @etairl) listed *`__proto__` prototype pollution in `MemorySaver`* among the unfiled findings from the same security-review pass that produced #2337. This PR confirms the finding and closes it across all five entry points. ## Vulnerable sinks `libs/checkpoint/src/memory.ts`: | Method | Sink | |---|---| | `put` | `this.storage[threadId][checkpointNamespace][checkpoint.id] = ...` | | `putWrites` | `this.writes[outerKey][innerKeyStr] = ...` (with caller-controlled `taskId` flowing into `innerKeyStr`) | | `deleteThread` | `delete this.storage[threadId]` | | `getTuple` | `this.storage[thread_id]?.[checkpoint_ns]?.[checkpoint_id]` | | `list` | `this.storage[threadId]?.[checkpointNamespace]` plus `Object.keys(this.storage[threadId] ?? {})` | ## Proof of concept \`\`\`ts import { MemorySaver } from \"@langchain/langgraph-checkpoint\"; const saver = new MemorySaver(); await saver.put( { configurable: { thread_id: \"__proto__\", checkpoint_ns: \"\" } }, /* checkpoint */ { id: \"cp-1\", v: 4, ts: new Date().toISOString(), channel_values: {}, channel_versions: {}, versions_seen: {} } as any, /* metadata */ { source: \"input\", step: 0, parents: {} } as any, {} ); // Object.prototype is now polluted; every plain object in the process // inherits the injected key. const probe: Record<string, unknown> = {}; console.log(\"polluted\" in probe); // true console.log(probe[\"\"]); // the (formerly per-tenant) saved checkpoint \`\`\` Same shape works for `\"constructor\"` and `\"prototype\"`. Non-string identifiers (`{ \$ne: null }`, arrays, numbers, booleans) reach the same sinks unchecked. ## Severity Proposed CVSS 3.1: **High**. `MemorySaver` is the default in every quickstart and tutorial, and prototype pollution in Node.js is a documented stepping stone to RCE through gadget chains in downstream serializers, template engines, and dependency-resolution helpers. Network-reachable, low-complexity, only the privilege the SDK already grants to a caller. ## Fix A single private `assertSafeStorageKey` helper in `memory.ts`, applied at every public entry that touches `storage` or `writes` (15 call sites across 5 methods). The guard: * Asserts the value is a non-empty string (the documented empty `checkpoint_ns` default is opt-in via `{ allowEmpty: true }`). * Rejects the three prototype-pollution keys `__proto__`, `constructor`, `prototype`. * The `getTuple` and `list` read paths intentionally allow an empty or undefined `checkpoint_id` so the documented \"fetch latest\" behaviour continues to work; both paths still reject the magic keys. \`\`\`ts const POLLUTION_KEYS = new Set([\"__proto__\", \"constructor\", \"prototype\"]); function assertSafeStorageKey( field: string, value: unknown, options: { allowEmpty?: boolean } = {} ): asserts value is string { /* type check, empty check, pollution check, all with precise diagnostics */ } \`\`\` The guard is a TypeScript `asserts` predicate so call-sites get type narrowing for free and the compiler enforces that no later code path uses an unvalidated identifier. ## Why this design * Mirrors the chokepoint pattern used in PR #2349 (`MongoDBSaver`) and PR #2350 (`RedisSaver` / `ShallowRedisSaver`). All three savers now share the same defensive posture at their boundary. * Single private function: it is impossible for a future call-site to forget validation, and the `asserts` annotation surfaces missed sites at compile time. * No new dependencies, no API changes for valid inputs, no behaviour change for any documented happy path. ## Test plan * [x] 22 new tests in `libs/checkpoint/src/tests/memory-pollution.test.ts` under `describe(\"MemorySaver prototype-pollution guard\")`, parameterised across all three pollution keys plus type / empty / accept paths for every entry point. Includes a cross-test invariant (`afterEach` snapshots `Object.getOwnPropertyNames(Object.prototype)`) that asserts pollution did not actually occur even if the guard had been absent. * [x] Existing checkpoint suite green (\`pnpm --filter @langchain/langgraph-checkpoint test\`, 93 of 93 including the 22 new ones). * [x] Lint clean (\`oxlint\`, 0 warnings, 0 errors on the changed files). * [x] Format clean (\`oxfmt --check\`). * [x] No new dependencies, no public API changes, no behaviour change for valid string identifiers. ## Disclosure Original finding credited to @etairl (audit posted in #2346). This PR was prepared for coordinated public disclosure since the audit list is already public. Happy to coordinate timing with a private GHSA if the maintainers prefer. Pairs with the two earlier sibling fixes from the same audit pass: * PR #2349 / GHSA-98xf-r82g-9mhx (MongoDB NoSQL injection) * PR #2350 / GHSA-x3wm-3wx7-g6xm (Redis KEYS / SCAN injection) --------- Co-authored-by: Nagendhra <nagendhra405@gmail.com> Co-authored-by: Christian Bromann <git@bromann.dev> Co-authored-by: Cursor <cursoragent@cursor.com> |

fix(sdk): fold forkFrom client-side and honor multitaskStrategy (#2447)
## Summary - Fold the SDK's top-level `forkFrom` into `config.configurable.checkpoint_id` client-side before sending `run.start`, so `forkFrom` never reaches the server and the fork target travels via the single legacy-compliant field used by the existing run endpoints. - Drop the server-side `forkFrom` normalization/promotion in both protocol-v2 reference servers (`ProtocolService.createOrResumeRun` and the embed protocol routes), reading the fork target solely from `config.configurable.checkpoint_id`. - Honor the caller's per-run `multitaskStrategy` (`reject` | `rollback` | `interrupt` | `enqueue`) instead of hardcoding `interrupt`, falling back to `enqueue` (the legacy stream-endpoint default, matching the Python protocol-v2 server) when omitted or unrecognized. |

fix(langgraph-checkpoint-redis): block KEYS / SCAN pattern injection via top-level identifiers (#2350)
## Summary Closes a Redis pattern-injection sink (CWE-77, CWE-943) in `RedisSaver` and `ShallowRedisSaver`. A caller able to shape `thread_id`, `checkpoint_ns`, `checkpoint_id`, or `task_id` (multi-tenant SDK deployments where the `RunnableConfig` originates from request input, or webhook payloads that flow into a persisted thread) can promote a string identifier into a Redis glob (`*`, `?`, `[...]`) and read, overwrite, or wipe checkpoints belonging to other tenants. The audit posted in #2346 (cc @etairl) listed *Redis key/glob injection in `RedisSaver` / `ShallowRedisSaver`* among the unfiled findings from the same security-review pass. This PR confirms the finding and extends the fix to all key-building sites in both savers. ## Vulnerable sinks `RedisSaver` (`libs/checkpoint-redis/src/index.ts`): | Method | Sinks | |---|---| | `getTuple` | `keys(\"checkpoint:\${threadId}:\${checkpointNs}:*\")` plus the direct \`json.get\` key | | `list` (fallback paths) | `keys(\"checkpoint:\${threadId}:\${checkpointNs}:*\")`, `keys(\"checkpoint:*:\${checkpointNs}:*\")` | | `put` | `\`checkpoint:\${threadId}:\${checkpointNs}:\${checkpointId}\`` plus the zset key | | `putWrites` | per-write key, zset key, checkpoint key | | `deleteThread` | `keys(\"checkpoint:\${threadId}:*\")`, `keys(\"writes:\${threadId}:*\")` | | `loadPendingWrites` | `keys(\"checkpoint_write:\${threadId}:\${checkpointNs}:\${checkpointId}:*\")` | `ShallowRedisSaver` (`libs/checkpoint-redis/src/shallow.ts`) has the same five public entry points plus the equivalent helper. ## Proof of concept ```ts import { createClient } from \"redis\"; import { RedisSaver } from \"@langchain/langgraph-checkpoint-redis\"; const client = createClient({ url: process.env.REDIS_URL! }); await client.connect(); const saver = new RedisSaver(client); // Tenant A and Tenant B persist checkpoints normally. await saver.put( { configurable: { thread_id: \"tenant-a\", checkpoint_ns: \"\" } }, /* checkpoint */ { id: \"cp-a\", v: 4, ts: new Date().toISOString(), channel_values: {}, channel_versions: {}, versions_seen: {} } as any, /* metadata */ { source: \"input\", step: 0, parents: {} } as any, {} ); await saver.put( { configurable: { thread_id: \"tenant-b\", checkpoint_ns: \"\" } }, { id: \"cp-b\", v: 4, ts: new Date().toISOString(), channel_values: {}, channel_versions: {}, versions_seen: {} } as any, { source: \"input\", step: 0, parents: {} } as any, {} ); // Attacker controls only the thread_id of their own request. // Without the guard, deleteThread expands the KEYS pattern to a glob // and deletes BOTH tenants' checkpoints. await saver.deleteThread(\"*\"); // Both \`cp-a\` and \`cp-b\` are gone. ``` The same shape (`\"*\"`, `\"tenant-?\"`, `\"tenant-[ab]\"`, `\"a\\b\"`) is accepted by every Redis pattern site in the table above. ## Severity Proposed CVSS 3.1: **High**. The most severe sink is `deleteThread`, which gives full availability impact across every tenant in the database, with confidentiality (`getTuple`, `list`) and integrity (`put`, `putWrites`) impacts on the other paths. Network-reachable, low-complexity, only the privilege the SDK already grants to a caller. ## Fix A single `assertSafeKeyComponent` helper exported from `./utils.js`, applied at every key-building site (27 calls across 2 saver files plus the helper export). The guard: * Asserts the value is a non-empty string (the documented empty `checkpoint_ns` default is opt-in via `{ allowEmpty: true }`). * Rejects the Redis pattern meta-characters `* ? [ ] \`. * Rejects the `:` delimiter that would otherwise corrupt the colon-delimited key structure. \`\`\`ts export function assertSafeKeyComponent( field: string, value: unknown, options: { allowEmpty?: boolean } = {} ): asserts value is string { const { allowEmpty = false } = options; if (typeof value !== \"string\") { /* precise diagnostic */ throw ... } if (!allowEmpty && value === \"\") { throw ... } if (REDIS_KEY_FORBIDDEN.test(value)) { throw ... } } \`\`\` The guard is a TypeScript \`asserts\` predicate so call-sites get type narrowing for free and the compiler enforces that no later code path uses an unvalidated identifier. ## Why this design * Mirrors the maintainers' existing primitive-only pattern (\`escapeRediSearchTagValue\`) in the same file. * Single chokepoint: it is impossible for a future call-site to forget validation. * No new dependencies, no API changes for valid inputs, no behavior change for any documented happy path. * Pairs with PR #2349 (NoSQL injection in MongoDBSaver) so both backends now share the same defensive posture at the saver boundary. ## Test plan * [x] 11 new tests under \`describe(\"assertSafeKeyComponent\")\` in \`libs/checkpoint-redis/src/tests/utils.test.ts\` covering accept and reject paths for every input shape (normal string, empty with and without \`allowEmpty\`, every Redis meta-character, colon delimiter, every wrong type). * [x] Existing \`escapeRediSearchTagValue\` suite still green (regression). * [x] Full suite green (\`pnpm --filter @langchain/langgraph-checkpoint-redis test\`, 21 of 21). * [x] Format clean on all 4 changed files (\`oxfmt\`). * [x] No new dependencies, no public API changes, no behavior change for valid string identifiers. ## Disclosure Original finding credited to @etairl (audit posted in #2346). This PR was prepared for coordinated public disclosure since the audit list is already public. Happy to coordinate timing with a private GHSA if the maintainers prefer. --------- Co-authored-by: Nagendhra <nagendhra405@gmail.com> Co-authored-by: Christian Bromann <git@bromann.dev> Co-authored-by: Cursor <cursoragent@cursor.com> |

refactor(sdk): drop StreamSubmitOptions.command and simplify forkFrom (#2443)
## Summary
- Remove `command` from `StreamSubmitOptions` and the
`submit-coordinator` resume-via-`submit` path so HITL resume goes
through `stream.respond()` only.
- Simplify `forkFrom` from `{ checkpointId: string }` to a plain
checkpoint id string across the SDK, protocol-v2 services, and docs.
- Update interrupt tests, examples (`HumanInTheLoopView`, branching
views), and React/Vue/Svelte/Angular JSDoc and migration/interrupt docs
to match.

fix(sdk): preserve apiUrl path prefix in stream transport URLs (#2441)
## Summary - Fix `toAbsoluteUrl` to concatenate `apiUrl` and path instead of using `new URL(path, base)`, which dropped path prefixes on proxied deployments. - Route WebSocket stream URL construction through `toAbsoluteUrl` for consistency with SSE transport. - Add unit and integration tests for proxied apiUrl paths, plus shared transport test helpers. |

fix(sdk): cancel runs on stop by default and add disconnect() (#2438)
## Summary
- `stream.stop()` now cancels the active run server-side by default
(`client.runs.cancel`) before disconnecting the client transport.
- Added `stream.disconnect()` as an alias for `stop({ cancel: false })`
for join/rejoin UIs.
- Introduced `StreamStopOptions` (`{ cancel?: boolean }`) on
`StreamController` and all v1 framework bindings (React, Vue, Svelte,
Angular).
- Updated `use-stream.md` and added controller unit tests for
cancel-on-stop and no-cancel-on-disconnect.

fix(sdk): avoid eager stream getter evaluation (#2434)
## Summary fix(sdk): avoid eager stream getter evaluation during spread This fixes a React `useStream` development-mode failure where passing the stream handle through components that clone or rest-spread props could accidentally read lazy getters. The guarded `history` getter still throws when explicitly accessed with `fetchStateHistory: false`, but object spread no longer trips that path or widens `streamMode` by touching optional accessors. ## Changes `@langchain/langgraph-sdk` - Marks optional `useStream` accessors (`history`, `experimental_branchTree`, `toolProgress`, `subagents`, `activeSubagents`) as non-enumerable on the returned stream handle. - Preserves explicit access behavior for those accessors, including the existing `history` guard and stream mode opt-in for `toolProgress`/`subagents`. - Adds React hook regression coverage for object spread, explicit getter access, and stream mode inference. |

fix(sdk): unwrap Command tool outputs and hide scoped task tools (#2435)
## Summary - Filter scoped deep-agent `task` dispatch events out of `sub.toolCalls` so subagent tool streams only show real worker tools. - Unwrap LangGraph `Command` payloads in `parseToolOutput` when they carry an embedded `ToolMessage`, so `tc.output` resolves to the actual tool result instead of raw graph state. - Share the scoped-task filter between client subagent handles and framework tool-call projections. |

fix(sdk): clear subgraph and subagent discovery on thread swap (#2430)
## Summary - Add `reset()` to `SubgraphDiscovery` and `SubagentDiscovery` to clear internal maps and committed store snapshots. - Call both resets from `StreamController.#teardownThread()` alongside existing per-thread resets (messages, tools, metadata). - Add unit tests for discovery `reset()` and a controller test that `hydrate(null)` clears subgraphs after lifecycle events. |

feat(supervisor): widen agents type to accept createAgent graphs (#2317)
## Summary - Add a broader `CompiledStateGraph<any, any, string, any, any>` to the `agents` union in `CreateSupervisorParams` - Graphs produced by `createAgent` from `langchain` (via `.graph`) are now accepted alongside existing `createReactAgent` graphs and `RemoteGraph` - The original `AnnotationRootT`-parameterized `CompiledStateGraph` type is preserved for backward compatibility ## Motivation The new `createAgent` API in the `langchain` package returns a `ReactAgent` whose `.graph` property is a `CompiledStateGraph` with a different state schema (`BuiltInState`) than the `MessagesAnnotation`-based state from `createReactAgent`. Since `createReactAgent` is deprecated in favor of `createAgent`, `createSupervisor` needs to accept both graph types. At runtime this already works — `makeCallAgent` types its `agent` parameter as `any` and only accesses `.name`, `.invoke()`, and optionally `.description`. The type constraint on the `agents` parameter was simply too narrow for the new API. ## Changes ### `@langchain/langgraph-supervisor` (`libs/langgraph-supervisor`) - Updated `CreateSupervisorParams.agents` type to include `CompiledStateGraph<any, any, string, any, any>` in the union alongside the existing strictly-typed `CompiledStateGraph` and `RemoteGraph` ## Test plan - [x] `pnpm build` passes for `@langchain/langgraph-supervisor` - [x] Consuming project using `createAgent` + `createSupervisor` compiles without errors - [x] Existing supervisor tests still pass --------- Co-authored-by: Christian Bromann <git@bromann.dev> |

fix(langgraph-checkpoint-redis): fix deleteThread using wrong key pattern for writes (#2208)
## Summary Fixes #2207 - Fix `deleteThread()` using incorrect `writes:` prefix instead of `checkpoint_write:` for write key deletion - Add missing cleanup of `write_keys_zset:` entries, matching the correct implementation in `ShallowRedisSaver` The bug was found by comparing `RedisSaver.deleteThread()` with `ShallowRedisSaver.deleteThread()` in `shallow.ts`, which correctly uses `checkpoint_write:` prefix and also cleans up zset keys. ## AI Disclosure This bug was identified through code review with AI assistance. The fix aligns the standard `RedisSaver` implementation with the existing correct `ShallowRedisSaver` implementation. --------- Co-authored-by: Christian Bromann <git@bromann.dev> |

fix(sdk): align AssembledToolCall typing with pre-v1 expectations (#2421)
## Summary - Split tool-call handles by consumer: - **Client SDK** (`ThreadStream.toolCalls`, subgraph/subagent projections): `ClientAssembledToolCall` with a promise-only `output` (resolves on success, rejects on error). Still exported as `AssembledToolCall` from `@langchain/langgraph-sdk/client` for script usage. - **Framework SDKs** (`stream.toolCalls`, `useToolCalls`, `injectToolCalls`): `AssembledToolCall` with plain reactive fields — `output: T | null`, `status`, and `error` — updated in place as events arrive so React/Vue/Svelte/Angular can render from snapshots without `await`, effects, or Suspense around promises. - Add generic `AssembledToolCall<TName, TInput, TOutput>` plus `id`/`args` aliases; point `InferToolCalls` at assembled streaming handles and add `AssembledToolCallFromTool` (exported as `ToolCallFromTool` from `@langchain/react`, `@langchain/vue`, `@langchain/svelte`, and `@langchain/angular`). - Rework `ToolCallAssembler` around a mutable internal handle and `toClientAssembledToolCall()` for client projections; framework stores the reactive handle directly. - Remove redundant `InferAssembledToolCalls` and deprecated `StateOf`; wire typed `toolCalls` / selector generics across all four framework packages. - Expand and align `createAgent`, `createDeepAgent`, and `langgraph` type tests across React, Vue, Svelte, and Angular; update examples, protocol-v2 integration tests, and Vue migration docs. |

fix(core): move @langchain/core back into being a peer dep (#2415)
`@langchain/langgraph-sdk@1.9.0` promoted `@langchain/core` from a dev dependency to a **runtime dependency**, which caused install-size metrics for `@langchain/langgraph` to jump from ~6 MB to ~40 MB for consumers who did not already have core installed (or who use `--legacy-peer-deps`). That happened because core pulls in heavy transitive deps such as `js-tiktoken` (~21 MB) and `zod` (~6 MB), even though `@langchain/langgraph` already lists core as a peer. This PR moves `@langchain/core` back to a **required peer dependency** on the SDK, matching `@langchain/langgraph` and the pre-1.9.0 SDK layout. Runtime behavior is unchanged for typical LangGraph apps that already install core; SDK-only installs no longer force core into the tree. Also switches `LangChainTracer` in `types.ts` to a type-only import so the tracer subpath is not pulled as a value import. |

fix(langgraph-checkpoint-mongodb): validate configurable checkpoint IDs (#2397)
## Summary Fixes #2351 This change hardens `@langchain/langgraph-checkpoint-mongodb` against object-based configurable input in checkpoint identifiers. It adds runtime validation for `thread_id`, `checkpoint_ns`, and `checkpoint_id` before any MongoDB query/write path uses these values, so operator-like payloads are rejected early with explicit errors. ## Changes ### `@langchain/langgraph-checkpoint-mongodb` - Added a shared `getStringConfigValue` runtime validator in [`libs/checkpoint-mongodb/src/checkpoint.ts`](libs/checkpoint-mongodb/src/checkpoint.ts). - Applied validation to `getTuple`, `list`, `put`, `putWrites`, and `deleteThread`. - Preserved existing behavior where `getTuple` returns `undefined` when `thread_id` is missing, while now rejecting non-string values. - Added regression tests in [`libs/checkpoint-mongodb/src/tests/checkpoints.test.ts`](libs/checkpoint-mongodb/src/tests/checkpoints.test.ts) for object/operator payloads across the affected methods. - Added a patch changeset for `@langchain/langgraph-checkpoint-mongodb`.

fix(sdk): retry connection failures before throwing ConnectionError (#2388)
## Summary This change updates SDK retry behavior so connection-related failures are retried instead of immediately aborting inside `onFailedAttempt`. When retries are exhausted, the final surfaced error is still coalesced to a `ConnectionError` with the existing LangGraph-specific guidance. A focused unit test was added to lock in this behavior. ## Changes ### @langchain/langgraph-sdk - Updated `AsyncCaller` connection-error handling to only throw `ConnectionError` on the final failed attempt (`retriesLeft === 0`), while allowing retries on earlier attempts. - Added a regression test covering retry count plus final `ConnectionError` coalescing for connection-refused/fetch-failed style errors. - Added a patch changeset for `@langchain/langgraph-sdk` documenting the retry/coalescing fix. |

fix(langgraph): surface structuredResponse parse failures in createReactAgent (#2339)
Closes Issue #2338 ## Problem When `createReactAgent` is called with `responseFormat`, the `generate_structured_response` node calls `model.withStructuredOutput(schema).invoke(...)`. Some parsers return `null`/`undefined` (instead of throwing) when the LLM produces JSON that is syntactically valid but does not satisfy the schema (e.g. a missing required field). The result was unconditionally assigned to the `structuredResponse` channel, so the agent silently resolved with `structuredResponse: undefined` — no error, no warning, no log. ## Fix Detect the `null`/`undefined` case in `generate_structured_response` and throw a descriptive error stating that the structured-output parser returned null/undefined and the model output did not satisfy the schema. This converts the silent failure into an explicit, debuggable error. The error does not include the raw model completion. The existing call shape (`withStructuredOutput(schema, options).invoke(...)`) returns only the parsed value. Switching to `{ includeRaw: true }` would surface the completion but (a) overrides any caller-supplied `includeRaw` in the existing options object and (b) relies on every chat-model implementation honoring `includeRaw` consistently, so it's left as a possible follow-up. ## Test Added `Throws when structured output parser returns null` in `libs/langgraph-core/src/tests/prebuilt.test.ts`. It spies on `withStructuredOutput` to return `null` (simulating the silent failure) and asserts the agent rejects with the new error message. The test runs inside the existing `describe.each([["v1"], ["v2"]])` block, so both agent versions are covered. --------- Co-authored-by: Voddam Vignesh <vignesh.voddam@gep.com> Co-authored-by: Christian Bromann <git@bromann.dev> |

chore: version packages (rc) (#2385)
This PR was opened by the [Changesets release](https://github.com/changesets/action) GitHub action. When you're ready to do a release, you can merge this and the packages will be published to npm automatically. If you're not ready to do a release yet, that's fine, whenever you add more changesets to main, this PR will be updated. ⚠️⚠️⚠️⚠️⚠️⚠️ `main` is currently in **pre mode** so this branch has prereleases rather than normal releases. If you want to exit prereleases, run `changeset pre exit` on `main`. ⚠️⚠️⚠️⚠️⚠️⚠️ # Releases ## @langchain/langgraph-api@1.2.2-rc.0 ### Patch Changes - Updated dependencies \[[`44746b1`](https://github.com/langchain-ai/langgraphjs/commit/44746b1a3b5b49737542b120b9e45d6f94181113), [`4cc6491`](https://github.com/langchain-ai/langgraphjs/commit/4cc6491844f21ed0fc737eaef8498133daa877f7), [`ae8af2d`](https://github.com/langchain-ai/langgraphjs/commit/ae8af2d75aef9a7bbd930d221d1ce03e7fbb90ad), [`4fd1e9f`](https://github.com/langchain-ai/langgraphjs/commit/4fd1e9f5720361a86a386a286ad8fcc824643280), [`2ad1aa4`](https://github.com/langchain-ai/langgraphjs/commit/2ad1aa48c6a3f45340b4833e6de555fdc7348d15), [`75e651b`](https://github.com/langchain-ai/langgraphjs/commit/75e651b9cff1a1e39ad6513b8a5e9b565b9ad7fe), [`f1d651a`](https://github.com/langchain-ai/langgraphjs/commit/f1d651ae14ca178f4a915ac853ba9b439cd55ba3)]: - @langchain/langgraph-sdk@1.9.3-rc.0 - @langchain/langgraph@1.3.1-rc.0 - @langchain/langgraph-ui@1.2.2-rc.0 ## @langchain/langgraph-cli@1.2.2-rc.0 ### Patch Changes - [#2389](https://github.com/langchain-ai/langgraphjs/pull/2389) [`40bcdab`](https://github.com/langchain-ai/langgraphjs/commit/40bcdab38fa495028d8eba68062e48079dbe9208) Thanks [@jdrogers940](https://github.com/jdrogers940)! - Adding support for pre-release versions in api_version. - Updated dependencies \[]: - @langchain/langgraph-api@1.2.2-rc.0 ## @langchain/langgraph@1.3.1-rc.0 ### Patch Changes - [#2376](https://github.com/langchain-ai/langgraphjs/pull/2376) [`4fd1e9f`](https://github.com/langchain-ai/langgraphjs/commit/4fd1e9f5720361a86a386a286ad8fcc824643280) Thanks [@hntrl](https://github.com/hntrl)! - fix(langgraph): prefer configurable assistant and graph IDs for runtime server info Update runtime `serverInfo` construction to read `assistant_id` and `graph_id` from `config.configurable` first, with fallback to `config.metadata` for compatibility.

fix(sdk): bind subagent namespace to execution scope via taskInput (#2390)
## Summary
When the SDK consumes a deepagents run over protocol-v2, the parent's
`task` tool call registers a subagent under `tools:<tool_call_id>` (e.g.
`tools:toolu_*`), but the subagent's pregel execution emits its
`values`/`messages`/`lifecycle` events at a **sibling** namespace
`tools:<pregel-uuid>` — not nested, no shared segment.
`SubagentDiscovery` tracked the trigger namespace, so
`useMessages(stream, subagent)` filtered the wrong scope and consumers
saw empty subagent cards while content streamed server-side.
The wire carries no first-class link between the two namespaces — the
lifecycle event's `trigger_call_id` is the Pregel UUID, not the
Anthropic `tool_call_id`.
## Approach
The server seeds the subagent's first state with
`HumanMessage(content=description)`, so an exact-equality match against
`taskInput` is deterministic. Adds:
- `#toolCallIdByTaskInput: Map<string, string[]>` — FIFO queue keyed by
taskInput, populated when a `task` tool call is registered.
- `#bindNamespaceByTaskInput` — on the first `values` event at a
`tools:<id>` namespace, look up the first HumanMessage text, shift the
matching `tool_call_id`, and seed `#taskIdByObservedNamespace`.
`#recordObservedWorkNamespace` promotes the namespace as before.
The queue handles parallel dispatches that share a description. Pregel
preserves dispatch order across executions, so FIFO pop attributes them
correctly.
## Known cliff edges (all silent — card stays empty)
- Wrapper middleware mutates the seeded HumanMessage before it reaches
the subagent.
- The HumanMessage uses multimodal content blocks instead of a string.
- A custom \`CompiledSubAgent\` state doesn't include a HumanMessage.
The upstream fix that eliminates the whole class is for langgraph's
\`_TasksLifecycleBase\` (or deepagents) to enrich the subagent's
lifecycle payload with \`cause: { tool_call_id }\`. That would replace
this bridge with a flat lookup.

fix(sdk): coalesce RootMessageProjection writes via setTimeout(0) (#2387)
## Summary Reworks `RootMessageProjection` batching to fix two regressions at once. The freeze that #2384 originally addressed: on refresh, mid-run join, or a rapidly-streaming subagent, many `messages`-channel events drain through the controller's `for await` pump as a microtask chain. Per-event `store.setState` calls fire `useSyncExternalStore` notifications per event, and after ~50 React's `nestedUpdateCount` guard trips with "Maximum update depth exceeded", permanently freezing the UI on the first few messages. The new regression #2384 introduced: its `MessageChannel`-based scheduler deferred the first event of every streaming burst past React's initial render. Initial submit looked frozen — no user message, no AI response — until refresh. This change keeps the coalescing (so the freeze stays fixed) but swaps the scheduler to `setTimeout(0)` with a `#flushScheduled` idempotency guard: - `handleMessage` / `applyValues` compute new `messages` / `values` synchronously and stage them in `#pendingMessages` / `#pendingValues`. `#indexById` and `#valuesMessageIds` mutate synchronously so subsequent same-tick calls see up-to-date positions. - One `setTimeout(0)` flush per tick commits the staged values to the store in a single `setState`. Bursts collapse to one notification; streaming events separated by network latency each flush on their own boundary. - `reset()` drops pending writes so thread swaps can't bleed staged state. No test-only flush flag on the projection — the existing tests gained `await drainFlush()` between mutations and assertions. ### New regression coverage A `scheduling` describe block guards both contracts: - streamed event commits within one macrotask (would fail on a deferral-chain scheduler — initial-submit freeze) - values snapshot commits within one macrotask (would fail on hydrate freeze) - 200-delta synchronous burst → fewer than 10 store notifications (would fail on per-event `setState` — long-replay freeze) - 50 sequential `applyValues` calls → fewer than 10 store notifications (would fail on hydrate per-event freeze) Both coalesce tests fail on a sync projection; both single-event tests fail on a multi-macrotask deferral chain. ## Release Note None |
