Severity

Low

Vulnerability

The runtime/agent_server.py file configures CORSMiddleware with allow_origins set via an environment variable or default array. The allow_credentials flag was omitted. While Starlette defaults to False if omitted, leaving it implicit is an overly permissive default structure, often flagged by static analyzers because future changes enabling broad origins without reviewing credentials could introduce vulnerabilities.

Impact

Explicitly defining allow_credentials=False strengthens the boundary between frontend clients and the API runtime, ensuring the server rejects any credentialed (cookies, TLS client certs, etc.) cross-origin requests by default. This reduces the risk of CSRF or unintended session exposure in multi-tenant or loosely defined CORS environments.

Fix

Added allow_credentials=False to the CORSMiddleware initialization in runtime/agent_server.py.

Validation

Ran bash scripts/ci/run_basic_ci.sh which succeeded. The API endpoints tests passed successfully (uv run pytest extraction/tests/test_api_endpoints.py), ensuring no regressions were introduced to endpoint behavior.

Risks

None. allow_credentials already defaulted to False within Starlette's implementation, so this change simply makes the intent explicit and secure-by-default for future maintenance without altering existing live behavior.
