Advisory

Source description from Wordfence Intelligence, credited to Krzysztof Zając.

The Coming soon and Maintenance mode WordPress plugin before 3.6.8 does not have authorisation and CSRF checks in its coming_soon_send_mail AJAX action, allowing any authenticated users, with a role as low as subscriber to send arbitrary emails to all subscribed users.
