ZITADEL Vulnerable to Account Takeover via DOM-Based XSS in Zitadel V2 Login_CVE-2025-67495

{
    "lastseen": "",
    "description": "ZITADEL is an open-source identity infrastructure tool. Versions 4.0.0-rc.1 through 4.7.0 are vulnerable to DOM-Based XSS through the Zitadel V2 logout endpoint. The /logout endpoint insecurely routes to a value that is supplied in the post_logout_redirect GET parameter. As a result, unauthenticated remote attacker can execute malicious JS code on Zitadel users\u2019 browsers. To carry out an attack, multiple user sessions need to be active in the same browser, however, account takeover is mitigated  when using Multi-Factor Authentication (MFA) or Passwordless authentication. This issue is fixed in version 4.7.1.",
