CVE-2026-22355Network attack vector

Stored script execution via forged requests

Published Jan 22, 2026 · Updated Jan 22, 2026

Cross-site request forgery in Greg Molnar Simple XML Sitemap 1.3 and earlier allows remote attackers to store script in WordPress. The CNA and its sole referenced advisory do not identify the request handler, attacker-controlled parameter, or missing anti-CSRF check that persists the payload. Exploitation requires a WordPress user to interact with attacker-controlled content while authenticated; the stored script then executes in a visitor's browser and can read or alter data available to that session.
