CVE-2026-40325Network attack vector

Content restoration via missing anti-CSRF validation

Published May 6, 2026 · Updated May 6, 2026

Cross-site request forgery in Masa CMS allows remote attackers to restore deleted content through an administrator's authenticated browser session. The cTrash.restore function accepts restoration requests without validating the anti-CSRF token and honors the attacker-supplied parentid value. Exploitation requires a logged-in administrator to load attacker-controlled content, after which deleted material can be restored into public locations or the site structure can be altered.
