CVE-2026-61736

LightRAG provides simple and fast retrieval-augmented generation. Prior to 1.5.4, the server defaults to CORSORIGINS= combined with allowcredentials=True in lightrag/api/lightragserver.py, causing Starlette CORSMiddleware to effectively whitelist every origin for credentialed cross-origin request...

CVE-2026-61740

LightRAG provides simple and fast retrieval-augmented generation. Prior to 1.5.4, when LightRAG is deployed with LIGHTRAGAPIKEY set but AUTHACCOUNTS unset, X-API-Key protection can be bypassed because lightrag/api/auth.py falls back to a hardcoded DEFAULTTOKENSECRET, /auth-status and /login can...
