Upgrade lightrag-hku to version 1.4.13 or higher.
Overview
lightrag-hku is a LightRAG: Simple and Fast Retrieval-Augmented Generation
Affected versions of this package are vulnerable to Improper Authentication via the file lightrag/api/config.py that uses a default JWT secret "lightrag-jwt-default-secret" when the TOKEN_SECRET environment variable is not set. The AuthHandler in lightrag/api/auth.py uses this secret to sign and verify tokens. An unauthenticated attacker can forge valid JWT tokens using the publicly known default secret and gain access to any protected endpoint.
