Advisory
Source description from Wordfence Intelligence, credited to Meher Sudhakar Abbireddi.
The FunnelKit – Funnel Builder for WooCommerce Checkout plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in all versions up to, and including, 3.15.0.5. This makes it possible for authenticated attackers, with Administrator-level access and above, to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php).
