Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - A flaw was found in Keycloak. When the configuration uses JWT tokens for authentication, the tokens are
 cached until expiration. If a client uses JWT tokens with an excessively long expiration time, for
 example, 24 or 48 hours, the cache can grow indefinitely, leading to an OutOfMemoryError. This issue could
 result in a denial of service condition, preventing legitimate users from accessing the system.
