The Coming soon and Maintenance mode WordPress plugin before 3.5.3 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
The web application does not, or cannot, sufficiently verify whether a request was intentionally provided by the user who sent the request, which could have originated from an unauthorized actor.
