NVD Description

Note: Versions mentioned in the description apply only to the upstream keycloak package and not the keycloak package as distributed by RHEL. See How to fix? for RHEL:10 relevant fixed versions and status.

Red Hat Keycloak before version 2.5.1 has an implementation of HMAC verification for JWS tokens that uses a method that runs in non-constant time, potentially leaving the application vulnerable to timing attacks.
