The 10Web Form Maker 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.
The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.
