PT-2026-59247

Summary 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,...

python-pyjwt: PyJWT: Verifier-side algorithm bypass leads to unauthorized information access

A flaw was found in PyJWT, a Python library for handling JSON Web Tokens JWT. An attacker with control over a registered JSON Web Key JWK private key can bypass security checks by signing a token with a forbidden algorithm while claiming to use an allowed one. This allows the attacker to have the...
