What is CVE-2026-3584?
CVE-2026-3584 is a critical code injection vulnerability in wpchill Kali Forms — Contact Form & Drag-and-Drop Builder, published on 20 Mar 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
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.
