Description

A flaw was found in Keycloak. An offline session continues to be valid when the offline_access scope is removed from the client.

Attack-Flow Graph

Executive Summary

This vulnerability in Keycloak allows an offline session to remain valid even after the offline_access scope is removed from the client. This means that the refresh token can still be used to request new tokens for the session, contrary to the administrator's expectation that removing the scope would disable offline sessions.

Impact Analysis

The vulnerability can lead to unauthorized continued access through offline sessions, as refresh tokens remain valid despite the removal of the offline_access scope. This could allow users or attackers to maintain access longer than intended, potentially leading to data exposure or unauthorized actions.
