 "title": "Kali Forms — Contact Form & Drag-and-Drop Builder <= 2.4.28 - Authenticated (Author+) Stored Cross-Site Scripting via Percent-Encoded Form Field Event Handler Property Names",
 "description": "The Kali Forms plugin for WordPress is vulnerable to Stored Cross-Site Scripting via form field property names in versions 2.4.27 up to, and including, 2.4.28, due to the guard that blocks JavaScript event-handler properties (onclick, other on* handlers and the Button clickAction) for users without the unfiltered_html capability checking the submitted property name instead of the name as it is stored. sanitize_text_field() later removes percent-encoded octets from that name. A name that only becomes a handler after this step is therefore saved, and the form is then allowed to output it. This makes it possible for authenticated attackers with author-level access and above to inject arbitrary web scripts into published forms that execute whenever a user views the form.",
