CVE-2026-16292Public exploitNetwork attack vector

File disclosure via nonce-free metadata update

Published Aug 2, 2026 · Updated Aug 2, 2026

Cross-site request forgery in N-Media Frontend File Manager Plugin 23.6 and earlier allows attackers to disclose uploaded files. The wpfm_file_meta_update AJAX action accepts a caller-supplied file ID and download hash without validating a WordPress nonce, then stores that hash as file metadata. Default configurations require a logged-in Subscriber or higher to visit attacker-controlled content; guest uploads expose the same write and download chain without authentication.
