What is CVE-2026-94000?

A security flaw in the Admin REST API of Keycloak allows a delegated administrator with limited permissions to gain unauthorized access to high-privilege groups. This occurs because the system does not properly verify if a group grants administrative rights before enabling a user to be added. This oversight can allow malicious users to elevate their permissions significantly, compromising the integrity and security of the entire realm.
