Red Hat Admin REST API of Keycloak: missing authorization
Medium6.6CVE-2026-94000 · Published Sep 19, 2026 · updated Sep 22, 2026
A flaw was found in the Admin REST API of Keycloak, an open-source identity and access management solution. The issue occurs in the group-membership endpoints where the system fails to check if a group grants administrative privileges before allowing a user to be added. This allows a delegated administrator with limited permissions to add themselves to a high-privilege group, potentially gaining full control over the entire realm.
