 "title": "Kali Forms — Contact Form & Drag-and-Drop Builder <= 2.4.26 - Authenticated (Author+) Stored Cross-Site Scripting via Form Field onclick Property",
 "description": "The Kali Forms plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the onclick and other on* event-handler field properties in all versions up to, and including, 2.4.26. The cause is that these properties were saved without restriction for users lacking the unfiltered_html capability and rendered into an onclick attribute on the front-end form, a JavaScript context where attribute escaping offers no protection. This makes it possible for authenticated attackers with Author-level access and above who can edit forms to inject arbitrary web scripts that execute whenever a user accesses a page containing the form.",
