CVE-2026-76604Network attack vector

Unauthenticated code execution via PHP form element

Published Aug 22, 2026 · Updated Aug 22, 2026

Code injection in Fabrik 1.0.0 through 4.7.1 allows remote attackers to execute arbitrary PHP code through a reachable Joomla form. The PHP form element's form_php::_runPHP path evaluates user-provided form content as PHP instead of treating submitted values as inert data. No account or user interaction is required; exposure requires a published Fabrik form that reaches the PHP element, and execution occurs in the Joomla server's PHP context.
