Privilege Escalation via Group Reparenting in Keycloak
CVE-2026-116468 Published on November 11, 2026
Keycloak-services: keycloak-services: delegated admin escalates to realm-admin via group move
A flaw was found in the group-move and organization group reparenting endpoints of the keycloak-services component. This component is responsible for core authentication and authorization services in the Red Hat build of Keycloak. The issue occurs because the system fails to check if a target parent group confers administrative roles when a group is moved. A delegated administrator can exploit this to move a group they control under an administrative group, causing all members to inherit full realm-admin privileges and gain complete control over the realm.
