LightRAG has a JWT Algorithm Confusion Vulnerability in LightRAG API

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.

LightRAG 数据伪造问题漏洞

LightRAG是中国香港大学数据智能实验室（HKU）开源的一款检索增强生成的应用程序。 LightRAG 1.4.14之前版本存在数据伪造问题漏洞，该漏洞源于存在JWT算法混淆攻击，可能导致攻击者通过指定none算法伪造令牌，造成未经授权的访问。
