Keycloak OrgMgmt API Bypass: Unauthorized Injection via Invitation Link
CVE-2026-16072 Published on July 17, 2026
Keycloak-services: keycloak-services: organization invitation link exposure allows unauthorized member creation
A flaw was found in the organization management component of Keycloak. A delegated administrator with permission to manage organizations can create an invitation for a non-existent email address and then retrieve the secret registration link directly through the application programming interface. By using this link, the administrator can create new user accounts and add them to the organization without having the required user management permissions or access to the invited email account. This allows an administrator to bypass security boundaries and add unauthorized members to an organization.
