CVE-2026-41430Network attack vector

Reflected XSS via unvalidated login redirect

Published Apr 24, 2026 · Updated Apr 24, 2026

Reflected XSS in the Press login page allows remote attackers to execute script through a crafted redirect parameter. LoginSignup.vue's afterLogin method assigns the untrusted redirect query value directly to window.location.href without limiting it to an internal path. Exploitation requires a user to follow a crafted login URL and complete login, after which attacker-supplied script runs in that user's browser context.
