Keycloak Admin UI REST Extensions: bulk role-removal endpoints fail to perform granular permission checks
CVE-2026-11986 · GHSA-6w3v-mcfh-m3q7
- Affected
- Maven org.keycloak:keycloak-rest-admin-ui-ext < 26.7.0
- Fixed in
- 26.7.0· Vendor fix available
- Issue
- 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.
Recommended action: Upgrade to 26.7.0 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
