Addresses remaining attack surface from security advisories:
GHSA-3qg8-5g3r-79v5 (JWT signing key - CRITICAL):
auth_service.py: PLATFORM_ENV no longer defaults to 'dev' when unset.
When PLATFORM_JWT_SECRET is not set and PLATFORM_ENV is not explicitly
'dev', an ephemeral random secret is auto-generated with a warning.
This prevents production deployments from silently using the well-known
'dev-secret-change-me' key.
GHSA-vg22-4gmj-prxw (unauthenticated eval - CRITICAL):
Replaced all eval() calls in official examples and benchmarks with an
AST-based safe math evaluator that only allows numeric literals and
arithmetic operators. Files fixed:
- examples/python/a2a/a2a-server.py (the primary advisory target)
- examples/mcp/multi_server.py
- examples/python/mcp/mcp-tools-server.py
- examples/python/mcp/mcp-tools-server-sse.py
- examples/mcp_server/custom_tools_server.py
- examples/python/mcp_server_example.py
- examples/python/custom_tools/tools_with_latency.py
- examples/eval/reliability_example.py
- src/praisonai-agents/benchmarks/real_benchmark.py
The character-filter approach (allowlist '0123456789+-*/.()') was
insufficient because () enables attribute access chains. AST-based
evaluation only permits numeric literals and binary/unary arithmetic.
GHSA-hvhp-v2gc-268q and GHSA-9cr9-25q5-8prj (file read/write):
Already fixed in prior commits via _resolve_rule_path() and
_resolve_cwd_yaml_path() containment helpers.
