CVE-2026-61736: LightRAG: CORS Wildcard + Credentials Enables Any-Origin Credentialed Requests
The server defaults to CORS_ORIGINS=* combined with allow_credentials=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 website can perform authenticated API calls on behalf of a logged-in user.
