Contact Form by Bit Form: Multi Step Form, Calculation Contact Form, Payment Contact Form & Custom Contact Form builder 2.0 - 2.13.9 - Authenticated (Administrator+) Arbitrary File Read And Deletion

The Contact Form by Bit Form: Multi Step Form, Calculation Contact Form, Payment Contact Form & Custom Contact Form builder plugin for WordPress is vulnerable to arbitrary file read and deletion due to insufficient file path validation in multiple functions in versions 2.0 to 2.13.9. This makes it possible for authenticated attackers, with Administrator-level access and above, to read and 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).
