CVE-2026-3584: Wpchill Kali Forms — Contact Form & Drag-And-Drop Builder

Critical severity, CVSS 9.8. EPSS: 4.4% chance of exploitation in the next 30 days.

The Kali Forms plugin for WordPress is vulnerable to Remote Code Execution in all versions up to, and including, 2.4.9 via the 'form_process' function. This is due to the 'prepare_post_data' function mapping user-supplied keys directly into internal placeholder storage, combined with the use of 'call_user_func' on these placeholder values. This makes it possible for unauthenticated attackers to execute code on the server.

Affected products

• Wpchill Kali Forms — Contact Form & Drag-And-Drop Builder: up to and including 2.4.9
