Received Received - Intake
Remote Code Execution in Kali Forms WordPress Plugin

Publication date: 2026-03-20

Last updated on: 2026-03-20

Assigner: Wordfence

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.

Executive Summary

The Kali Forms plugin for WordPress has a vulnerability in all versions up to and including 2.4.9 that allows Remote Code Execution (RCE). This happens because the 'prepare_post_data' function maps user-supplied keys directly into internal placeholder storage, and then the 'call_user_func' function is used on these placeholders. As a result, an unauthenticated attacker can execute arbitrary code on the server.

Impact Analysis

This vulnerability can have severe impacts because it allows unauthenticated attackers to execute arbitrary code on the server hosting the WordPress site. This can lead to full compromise of the server, including data theft, data loss, service disruption, and unauthorized access to sensitive information.
