Official description

The SMTP2GO for WordPress – Email Made Easy plugin for WordPress is vulnerable to unauthorized access in all versions up to, and including, 1.16.0. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with subscriber-level access and above, to truncate all SMTP2GO log records from the database or download a CSV export of all SMTP log data including recipient addresses, sender addresses, message subjects, and API response data.
