Contact Form by WD 1.13.1 contains a cross-site request forgery vulnerability combined with local file inclusion that allows unauthenticated attackers to include arbitrary files by exploiting unsanitized action parameters. Attackers can craft malicious forms targeting the admin-ajax.php endpoint with directory traversal sequences in the GET action parameter to load files via CSRF, bypassing authentication on vulnerable AJAX actions.
