CVE-2022-4136Public exploitNetwork attack vector

Unauthenticated code execution via GET-controlled method dispatch

Published Nov 24, 2022 · Updated Apr 14, 2025

Exposed method dispatch in Leadshop before 1.4.16 allows remote attackers to execute server-side code through a crafted GET request. The run method in web/leadshop.php passes the GET-controlled include value to call_user_func_array as a method name without an allowlist. No authentication or user interaction is required, and exploitation grants host control through arbitrary callable methods.
