Asymmetric denial of service In org.keycloak:keycloak-services
Description
Keycloak Denial of Service (DoS) Vulnerability via JWT Token Cache 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.
