Keycloak-services: keycloak-services: required actions bypassed via kc_action parameter

Published Oct 30, 2026 · Updated Nov 3, 2026 · Assigned by redhat

Description

A flaw was found in the required action provider mechanism of Keycloak. The issue occurs when an authorization request includes the kc_action query parameter set to a mandatory action already assigned to the user, such as profile verification or terms and conditions. Due to incorrect handling of application-initiated actions, Keycloak may skip these mandatory challenges and issue an authorization code. This can allow a user to bypass administrative requirements and gain access to the application without completing necessary profile updates or agreeing to terms.
