+## Summary
+
+Nuclei's historical security posture is dominated by sandbox escapes and code execution via unsigned or unverified templates, with recurring SSRF, path traversal, and auth bypass issues across JS libraries, loaders, and workflow paths. The most critical theme is inconsistent enforcement of signature verification and local-file-access (-lfa) guards across direct, workflow, DAST, and JS-sandbox entry points, enabling variant attacks. A second theme is network policy (host allowlist) gaps in LDAP dialing and proxy handling. The security context also includes dependency upgrades (Alpine, go-git) and output file permission hardening, but the highest-value focus is on template trust boundaries and sandbox enforcement parity.

-Real security fixes mined from git history; use them as regression checks. `verified` fixes are linked to a published advisory, `inferred` fixes were confirmed from the diff evidence alone. Each is identified by its short commit SHA, which the variant-leads report uses to reference it back to this history.

-**By component** (directories with the most fixes):
+Unsigned templates can execute code through direct loading, workflows, and DAST branches; signature verification was bypassed via cache poisoning and missing guards on specific paths.

+
+## Shared Attack Surfaces
+
+Capabilities guarded by more than one past fix on different code paths. A guard enforced on one entry point is often missing on a sibling; verify each alternate path before assuming it's covered.
+
+### 1. Template signature verification and unsigned-template opt-in enforcement across all load paths
+
+- Guard that should hold everywhere: signature verification (template.Verified, Verify), DisableUnsignedTemplates flag, -code flag for code templates, cache invalidation on verification status/fingerprint/digest
+- Entry points: `pkg/catalog/loader/loader.go (LoadTemplatesWithTags, DAST branch)`, `pkg/templates/workflows.go (loadTemplates, workflowExecutor)`, `pkg/templates/templates.go (loadTemplates)`, `pkg/templates/compile.go (template.Verified)`, `pkg/templates/signer/tmpl_signer.go (Verify)`
+- Check: Inspect the DAST and workflow sub-loaders: they must enforce the same DisableUnsignedTemplates and -code checks as the direct loader, and must not rely on cached verification results without re-checking signatures.
+- Evidence: 9de96e4dda5a03da963b9ae6582f03ea55791a76, 1c440e755a97471c56fb0276ee8a8c4132974645, fac0b7196d2fbca56c8af8ff8e1899c111041a37, e86f38299765b82ad724fdb701557e0eaff3884d, fa56800fcca3c8c8fe8e8dec28584210ca1527de, 4534e9cb3034ebe5cc7b0cecabe399b6fb9ce0e4, 0da993afe6d41b4b1b814e8fad23a2acba13c60a, 9bd4db3f74aedd067af568df4f9198a8a090f68b
+
+### 2. Local file access (read/write) outside the sandbox, gated by -lfa flag
+
+- Guard that should hold everywhere: -lfa flag enforcement, path canonicalization and containment (sandbox directory), file:// scheme blocking, allowAllFiles stripping, require() registry rebuild
+- Entry points: `pkg/js/libs/krbforge/krbforge.go (CreateTicket)`, `pkg/js/libs/mysql/mysql_private.go (sql.Open)`, `pkg/js/compiler/pool.go (require)`, `v2/pkg/protocols/javascript/js.go (ReadFile, eval)`, `v2/pkg/protocols/common/protocolstate/headless.go (file:)`, `v2/pkg/protocols/common/generators/load.go (loadPayloadsFromFile)`
+- Check: Verify that every JS library and protocol helper (krbforge, mysql, require, headless file://, payload loaders) enforces the -lfa flag and path containment; a sibling path that skips the -lfa check is a sandbox escape.
+- Evidence: 3a8b65cb45f121fcdf418f60e5177ed9f250c122, 9611926a9a1ca99e8ed554d1b26fbeff60e06368, 6f2ade6a9b427c284c15a43445f9c7f055e60e5d, c35162c8ef061a96dd74b54c8f022c1a41cf5833, d3928e080d819f25306bfbaecc399f03516db5aa, e7fb40a41308f6c41267e858d1781eb67f7e0572
+
+### 3. Network policy (host allowlist) enforcement before outbound connections
+
+- Guard that should hold everywhere: IsHostAllowed check on the actual target host (controller, not domain), proxy validation and connectivity check, ProxyInternal gate for HTTP_PROXY env
+- Entry points: `pkg/js/libs/ldap/ldap.go (Dial, newLdapSession)`, `v2/internal/runner/proxy.go (loadProxyServers, os.Setenv HTTP_PROXY)`
+- Check: Inspect other dialing paths (e.g., HTTP, headless) to ensure they apply the same host allowlist check on the resolved IP/host, not just a user-supplied domain, and that proxy settings cannot redirect traffic to internal hosts.
+- Evidence: 9def9af7e3f7ebcf5cd561c37b623b9999ee7572, a167e6c57b80f5dc7be231231b62d7c594ee2770, 0e46d3e0410f89e4af41099f5cd38fa7f54ae54f, 3f5c055aca1499642caf4f40e8cf55ad32bd4da9
+
+### 4. Path traversal in file extraction and template path trust boundaries
+
+- Guard that should hold everywhere: canonical path containment check (filepath.Rel, prefix), zip-slip validation against template directory, sandbox path prefix validation
+- Entry points: `pkg/catalog/config/nucleiconfig.go (IsCustomTemplate)`, `v2/internal/runner/update.go (os.OpenFile)`, `v2/pkg/protocols/common/generators/load.go (loadPayloadsFromFile)`
+- Check: Audit all file-write and file-read paths that accept template-controlled paths (e.g., template extraction, payload loading) to ensure they use canonical containment, not lexical prefix checks, and apply the same sandbox directory restriction.
+- Evidence: 20cbf0bd73893c1270582c9778b6b26a5cb11206, f9c214a66f37a00fc29fe64232b690e6285ec59c, e7fb40a41308f6c41267e858d1781eb67f7e0572
