Keycloak-rest-admin-ui-ext: authorization bypass vulnerability in the admin-ui-ext bulk role-mapping-delete endpoints of keycloak_CVE-2026-11986

{
    "lastseen": "",
    "description": "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.",
