CVE-2019-11591

Exp

The WebDorado Contact Form plugin before 1.13.5 for WordPress allows CSRF via the wp-admin/admin-ajax.php action parameter, with resultant local file inclusion via directory traversal, because there can be a discrepancy between the $_POST['action'] value and the $_GET['action'] value, and the latter is unsanitized.
