The Visitors Traffic Real Time Statistics Pro plugin for WordPress is vulnerable to unauthenticated stored Cross-Site Scripting in all versions up to, and including, 11.22 via the page_title parameter of the ahcpro_track_visitor AJAX action. The action is registered for logged-out callers (wp_ajax_nopriv_ahcpro_track_visitor) and stores $_POST['page_title'] with NO sanitization, keeping it raw in the ahc_title_traffic.til_page_title column. When an administrator opens the plugin's dashboard, the 'Traffic by Title' DataTable renders that stored value as innerHTML without output escaping, executing arbitrary JavaScript. This makes it possible for unauthenticated attackers to inject web scripts that run in an administrator's session.
