Kali Forms < 2.4.29 - Author+ Stored XSS via Button Click Action

The Kali Forms — Contact Form & Drag-and-Drop Builder WordPress plugin before 2.4.29 does not prevent users with author-level access and above from storing arbitrary JavaScript in a form button configuration, which is later output into a JavaScript execution context and runs in the browser session of any user who clicks the button, including an administrator.
