It was found that the Keycloak Node.js adapter 2.5 - 3.0 did not handle invalid tokens correctly. An attacker could use this flaw to bypass authentication and gain access to restricted information, or to possibly conduct further attacks.
Weakness
The product incorrectly checks a return value from a function, which prevents it from detecting errors or exceptional conditions.
