Kerentanan Authorization Bypass Through User-Controlled Key pada redhat build of keycloak. Skor CVSS 3.1 4.9 (Medium) menurut redhat.com.

Deskripsi (NVD)

A flaw was found in the RoleContainerResource component of Keycloak. The issue occurs because certain name-based endpoints in the admin REST API do not properly enforce authorization checks when managing composite roles. This allows a delegated administrator with manage-realm permissions to remove essential child roles from built-in admin roles, potentially disrupting administrative functions within a realm.
