PYSEC-2026-3474 LightRAG: CORS Wildcard + Credentials Enables Any-Origin Credentialed Requests

Summary The server defaults to CORSORIGINS= combined with allowcredentials=True. Starlette's CORSMiddleware echoes the requesting origin in preflight responses when credentials are enabled, meaning every origin is effectively whitelisted for credentialed cross-origin requests. Any malicious websi...

PYSEC-2026-3475 LightRAG is Vulnerable to Authentication Bypass: hardcoded DEFAULT_TOKEN_SECRET and public /auth-status defeat LIGHTRAG_API_KEY protection

Summary When LightRAG is deployed with LIGHTRAGAPIKEY set but AUTHACCOUNTS unset an officially documented "API-Key authentication" mode, the X-API-Key protection can be bypassed by any remote unauthenticated attacker. The bypass does not require network contact with the victim server — an attacke...
