CVE-2026-11986

4.9 mediumEPSS 0.3%

Medium (4.9) in redhat build of keycloak. EPSS 0.3% chance of exploitation in the next 30 days. Fixed in org.keycloak:keycloak-rest-admin-ui-ext 26.7.0.

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.
