CVE-2025-67495Network attack vector

Account takeover via unvalidated logout redirect

Published Dec 9, 2025 · Updated Dec 10, 2025

DOM-based XSS in ZITADEL Login V2 4.0.0-rc.1 through 4.7.0 allows remote attackers to run JavaScript through the logout endpoint. The /logout route passes an unvalidated post_logout_redirect query value to client-side navigation, allowing a JavaScript URL to execute in the ZITADEL origin. Exploitation requires user interaction and multiple active sessions in one browser; MFA or passwordless authentication limits the reported account-takeover consequence.
