The Campaign Monitor for WordPress plugin for WordPress is vulnerable to Full Path Disclosure in all versions up to, and including, 2.8.15. This is due the plugin not properly restricting direct access to /forms/views/admin/create.php and display_errors being enabled.

The information displayed is not useful on its own, and requires another vulnerability to be present for damage to an affected website.
