Keycloak Auth Services: Admin Bypass Reveals Full User Profiles
CVE-2026-94213 Published on September 21, 2026
Keycloak-services: keycloak-services: authorization services policy evaluation endpoint leaks user identity
A flaw was found in the Authorization Services component of Keycloak, an open-source identity and access management solution. The issue occurs in the policy evaluation endpoint, which is used by administrators to test how access policies apply to specific users. Due to missing authorization checks, a delegated administrator with limited viewing privileges can access the full profile and role information of any user in the realm, even if they are not permitted to view user details. This could lead to the exposure of sensitive information such as email addresses and assigned security roles.
