CVE-2022-29454Network attack vector

Unauthenticated file upload via forged message request

Published Jul 20, 2022 · Updated Apr 28, 2026

Cross-Site Request Forgery in WordPlus Better Messages 1.9.9.148 and earlier allows remote attackers to upload files via crafted requests. The message attachment upload handler accepts a cross-site request without validating a CSRF nonce, so a browser carrying a privileged WordPress session can be induced to submit the upload. Exploitation requires file attachments to be enabled and user interaction with attacker-controlled content; the result is attacker-controlled file placement, with broader execution impact dependent on server handling.
