Order Export & Order Import for WooCommerce <= 2.7.8 - Unauthenticated Sensitive File Exposure via Missing Directory Guard Re-verification in get_file_path()

The Order Export & Order Import for WooCommerce plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 2.7.8 via the get_file_path. This makes it possible for unauthenticated attackers to extract download exported order CSV files containing customer PII — including names, billing and shipping addresses, email addresses, phone numbers, and order contents — directly over HTTP with no authentication. This is exploitable whenever the .htaccess and index.php guard files are absent from wp-content/webtoffee_export/, which can occur after any uninstall/reinstall cycle, migration, backup restore, or staging sync, since the export directory persists but its guard files do not; export filenames follow a fully deterministic second-precision timestamp pattern, making them brute-forceable across any suspected export window.
