Keycloak: org.keycloak/keycloak-services: keycloak: privilege escalation via manage-clients permission

Published Mar 26, 2026 · Updated Apr 2, 2026 · Assigned by redhat

Description

A flaw was found in Keycloak. An administrator with `manage-clients` permission can exploit a misconfiguration where this permission is equivalent to `manage-permissions`. This allows the administrator to escalate privileges and gain control over roles, users, or other administrative functions within the realm. This privilege escalation can occur when admin permissions are enabled at the realm level.
