CVE-2026-11986
MEDIUMRed Hat Keycloak admin-ui-ext - Authorization Bypass in Bulk Role Mapping Deletion
Title source: manualDescription
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.
