EXECUTIVE SUMMARY:
The Kali Forms plugin for WordPress contains a critical remote code execution vulnerability CVE-2026-3584 that allows unauthenticated attackers to execute arbitrary code on affected servers. The flaw originates from improper handling of user-supplied input within the form processing functionality, where input data is directly mapped into internal placeholders and executed through unsafe function calls. This lack of validation and secure execution controls enables attackers to craft malicious requests that trigger code execution without requiring authentication. Successful exploitation can lead to complete website compromise, including unauthorized access to sensitive data, deployment of backdoors or malware, and full control over the underlying server environment. The vulnerability is particularly severe due to its network-based attack vector, low complexity, and absence of authentication requirements, making it highly exploitable at scale. The vulnerability has a CVSS score of 9.8.[/subscribe_to_unlock_form]
