Advisory

Source description from Wordfence Intelligence, credited to TP Cyber Security.

The WP EXtra plugin for WordPress is vulnerable to unauthorized access to restricted functionality due to a missing capability check on the 'test-email' section of the register() function in versions up to, and including, 6.2. This makes it possible for authenticated attackers, with minimal permissions such as a subscriber, to send emails with arbitrary content to arbitrary locations from the affected site's mail server.
