ARforms is a WordPress form-builder plugin used to create and manage web forms. An unauthenticated attacker can inject malicious scripts into form entries by manipulating the HTTP Referer header, causing the scripts to execute in the browsers of any user who views the affected page.

The vulnerability is a stored cross-site scripting (XSS) flaw in the arf_save_incomplete_form_data() AJAX handler, which is registered with wp_ajax_nopriv_ to allow unauthenticated access. The handler fails to properly sanitize and escape the Referer header before storing it in the database, allowing attackers to submit a partial form with a forged Referer header containing JavaScript payloads that persist and execute whenever the stored entry is viewed.
