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."}], "lastModified": "2026-06-11T20:56:29.653", "sourceIdentifier": "secalert@redhat.com"}
