…S#3807) The jwt_db_authorize() function... The jwt_db_authorize() function in the auth_jwt module decodes JWT tokens without signature verification to extract the 'tag' claim, then interpolates this claim directly into a raw SQL query without escaping. An attacker can craft a malicious JWT with SQL injection payload in the tag claim (e.g., "' UNION SELECT 'admin','attacker_secret' --") to inject their own secret into the query result. Since the injected secret is then used to verify the JWT signature, the attacker can sign their token with this known secret and achieve authentication bypass.
