Arbitrary file upload via forged administrator request
Published Oct 16, 2024 · Updated Apr 8, 2026
Cross-site request forgery in File Manager Pro 8.3.9 and earlier allows remote attackers to upload arbitrary files via forged requests. The mk_file_folder_manager AJAX action accepts file-upload operations without valid nonce verification, allowing attacker-controlled content to execute in an administrator's authenticated WordPress session. Exploitation requires administrator interaction with a crafted link or page; the resulting unauthorized upload writes attacker-chosen files to the WordPress server.
