 "title": "Kali Forms — Contact Form & Drag-and-Drop Builder <= 2.4.31 - Unauthenticated Reflected Cross-Site Scripting via Form Submission Response",
 "description": "The Kali Forms plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the form submission response of the kaliforms_form_process AJAX action in all versions up to, and including, 2.4.31. This is due to the form processor returning its responses through wp_die(wp_json_encode(...)), which admin-ajax.php serves as text/html, without hex-escaping HTML characters. These responses echoed request-supplied values unsanitized, including the raw submitted form data and the admin_stop_reason and error_bag values, which the processor accepted from visitors. This makes it possible for unauthenticated attackers to inject arbitrary web scripts that execute in a victim's browser if they can trick a user into performing an action such as submitting a crafted form. In versions that require the form nonce, the attack works against visitors who are not logged in, because the nonce for logged-out visitors can be read from any public form page.",
