Description
The MailChimp Forms by MailMunch plugin for WordPress is vulnerable to unauthorized modification of data and loss of data due to a missing capability check on the 'delete_widget', 'change_email_status', and 'delete_email' AJAX functions in versions up to, and including, 3.1.4. This makes it possible for authenticated attackers, with subscriber-level access and above, to delete widgets and change or delete arbitrary email subscriber records.
