TIMELINE

Aug 25 Published (CNA: redhat)
Sep 16 PATCH SHIPPED — CVE-2026-79652 (Red Hat build of Keycloak 26.6). Fixed in Red Hat build of Keycloak 26.6 26.6.7-3.
Description
A flaw was found in the JWT Bearer authorization grant implementation within the keycloak-services component of Red Hat Build of Keycloak. This component handles various OAuth2 and OpenID Connect grant types used for issuing access tokens. The issue occurs because the JWT Bearer grant fails to check if a client requires user consent before issuing a token. This allows an authenticated attacker with valid client credentials and a trusted identity provider assertion to bypass the consent requirement and obtain unauthorized access to a user account at a consent-gated client.
