Overview
lightrag-hku is a LightRAG: Simple and Fast Retrieval-Augmented Generation
Affected versions of this package are vulnerable to Use of Hard-coded Credentials in the authentication process when a hardcoded default token secret is used and certain endpoints such as /auth-status and /login are exposed without proper authentication checks. An attacker can gain unauthorized access to protected API endpoints and perform destructive actions, such as reading, deleting, or uploading documents, clearing caches, and running arbitrary queries, by minting a valid guest JWT offline or obtaining one from the unauthenticated endpoints. This is only exploitable if the server is configured with LIGHTRAG_API_KEY set and AUTH_ACCOUNTS unset.
