CVE-2025-13308Network attack vector

Browser script execution via unchecked reject_url

Published Dec 6, 2025 · Updated Apr 8, 2026

Reflected XSS in George Stephanis Application Passwords 0.1.3 and earlier allows remote attackers to execute scripts via reject_url. The auth_app_page method passes the unfiltered GET value into authApp.reject, and the auth-app.js rejection handler assigns it directly to window.location without rejecting javascript schemes. Exploitation requires a logged-in user to open the crafted authorization page and click the rejection button, enabling browser-context data access or modification.
