Unauthenticated file read via unchecked email attachment path
Published Jul 2, 2026 · Updated Jul 2, 2026
Path traversal in Saturday Drive Ninja Forms File Uploads 3.3.29 and earlier allows remote attackers to read server files through email attachments. When a client-supplied saveProgress flag makes process() return early, get_files_for_attachment() trusts files[].data.file_path and passes it to wp_mail() after only file_exists(). No account is required, and reachability requires a form email action configured to attach uploaded files readable by the WordPress process.
