Vulnerability Overview

The Easy WP SMTP plugin for WordPress is vulnerable to Arbitrary File Deletion versions up to, and including, 1.5.1. This is possibly due to the SMTP import/export functionality. This makes it possible for administrator-level attackers to arbitrarily delete files on the server, including critical files for the website's functionality.
