What is CVE-2026-16072?

A security flaw in Keycloak's organization management allows delegated administrators to invite a non-existent email address and access a secret registration link via the API. This functionality enables them to create user accounts without having the necessary permissions, effectively bypassing organizational security measures. As a result, unauthorized users can be added to the organization, posing significant security risks.
