CVE-2026-79652Network attack vector

User account access via missing consent check

Published Aug 25, 2026 · Updated Aug 25, 2026

Authorization bypass in Red Hat build of Keycloak allows remote authenticated users to access consent-gated user accounts. The JWT Bearer grant in keycloak-services issues an access token without checking the client's consentRequired flag, so a required user-consent decision is skipped. Exploitation requires valid client credentials, a trusted identity-provider assertion, and a non-default consent-gated client; success grants access as the target user.
