CVE-2026-92358Network attack vector

Account takeover via uncleared account-link proof

Published Sep 16, 2026 · Updated Sep 16, 2026

Red Hat build of Keycloak and Red Hat Single Sign-On 7 allow remote attackers controlling an external identity to take over accounts. The first-broker-login flow creates a temporary cross-browser linking proof but fails to clear it after linking or later unlinking the identity. The attacker must control the external identity and the victim must confirm an account link from another browser; the retained proof then permits silent relinking without another confirmation.
