CVE-2026-16106Keycloak-services: keycloak-services: incorrect authorization in admin role-composite deletion allows delegated admin to remove privileged child roles

Updated under an hour ago ()

Does this affect you?

It affects Red Hat build of Keycloak 26.6 and 4 other products. Add what you run to find out whether that includes you.

No exploitation reported and no EPSS estimate yet.

A flaw was found in the admin REST API of Keycloak, a solution for identity and access management. The issue occurs when a delegated administrator attempts to remove a child role from a composite role. Due to missing authorization checks, an attacker with limited administrative permissions can remove privileged roles they are not authorized to manage, leading to a loss of access for other users and administrators.
