CVE-2022-3126Network attack vector

Logged-in file upload via missing CSRF check

Published Oct 17, 2022 · Updated May 14, 2025

Cross-Site Request Forgery in Frontend File Manager Plugin before 21.4 allows remote attackers to make logged-in users upload files via forged requests. The wpfm_upload_file upload handler lacks effective nonce validation, so a crafted request issued by a logged-in browser performs the upload under that user's session. Exploitation requires user interaction and changes server-side files; the record does not establish direct data disclosure or service interruption.
