NVD Description

Note: Versions mentioned in the description apply only to the upstream keycloak-26.2 package and not the keycloak-26.2 package as distributed by Chainguard. See How to fix? for Chainguard relevant fixed versions and status.

A flaw was found in Keycloak. An offline session continues to be valid when the offline_access scope is removed from the client. The refresh token is accepted and you can continue to request new tokens for the session. As it can lead to a situation where an administrator removes the scope, and assumes that offline sessions are no longer available, but they are.
