A flaw was found in the admin-ui-ext component of Keycloak, which provides extended administrative user interface capabilities. The issue occurs because certain bulk role-removal endpoints fail to perform granular permission checks when deleting role mappings. This allows a delegated administrator with limited permissions to remove highly privileged roles from other users or groups, potentially disrupting administrative access control.
