Forminator Forms – Contact Form, Payment Form & Custom Form Builder <= 1.44.2 - Unauthenticated Arbitrary File Deletion Triggered via Administrator Form Submission Deletion

The Forminator Forms – Contact Form, Payment Form & Custom Form Builder plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the 'entry_delete_upload_files' function in all versions up to, and including, 1.44.2. This makes it possible for unauthenticated attackers to include arbitrary file paths in a form submission. The file will be deleted when the form submission is deleted, whether by an Administrator or via auto-deletion determined by plugin settings. This can easily lead to remote code execution when the right file is deleted (such as wp-config.php).

Requests carrying this pattern arrive without a session, so nothing upstream of the firewall gets a chance to reject them: WordSec's web application firewall inspects request payloads before WordPress loads them. Classes like this one can leave something behind, so the staged malware scanner is the second half: it looks for dropped files and modified code rather than for the request that created them. None of that substitutes for the fix: Forminator Forms 1.44.3 closes this, and updating the plugin is the step that ends it.
