Description
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.
