JWT authentication bypass via weak HMAC secret in Ever Gauzy v0.281.9
Ever Gauzy v0.281.9 contains a JWT authentication weakness stemming from an insecure/weak HMAC secret key implementation used for JWT signing/verification. An attacker who can obtain an exposed JWT can leverage the weak secret/verification to forge or otherwise produce a validly-signed token, allowing authentication as a higher-privileged user and resulting in unauthorized administrative access.
