Keycloak Denial of Service (DoS) Vulnerability via JWT Token Cache

發布日:2025/3/25修改日:2025/4/30
也稱為:GHSA-2935-2wfm-hhpv

描述

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.
