Kerentanan Improper Verification of Cryptographic Signature pada hkuds lightrag. Skor CVSS 3.1 6.5 (Medium) menurut NVD.

Deskripsi (NVD)

LightRAG provides simple and fast retrieval-augmented generation. Prior to 1.4.14, the LightRAG API is vulnerable to a JWT algorithm confusion attack where an attacker can forge tokens by specifying 'alg': 'none' in the JWT header. Since the jwt.decode() call does not explicitly deny the 'none' algorithm, a crafted token without a signature will be accepted as valid, leading to unauthorized access. This vulnerability is fixed in 1.4.14.
