Forminator Forms < 1.44.3 - Unauthenticated Arbitrary File Deletion Triggered via Administrator Form Submission Deletion

Description

The plugin is vulnerable to arbitrary file deletion due to insufficient file path validation in the 'entry_delete_upload_files' function. 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).
