Keycloakでクライアント管理権限を持つ管理者が、サーバー上で任意のコードを実行できる脆弱性が公表されました。Red Hat製品の利用組織は、告知で修正版を確認し、管理権限を持つアカウントを見直してください。

Original description The description as published by the source.

A flaw was found in the Keycloak server's client management component. When a client is created or imported with authorization services enabled, the system fails to properly clear an internal session attribute used during the setup process. This allows an authenticated attacker with client management permissions to bypass security controls and upload a malicious JavaScript policy, which is then executed on the server when an authorization request is made. Successful exploitation could allow the attacker to run arbitrary code on the server, potentially compromising the entire system.
