This vulnerability stems from insecure handling of form submissions. Instead of securely loading form definitions from the backend, the plugin accepts arbitrary form definitions directly from user input. Specifically, when the \u003ccode\u003e$_POST['_acf_form']\u003c/code\u003e parameter is an array (rather than a form ID), the \u003ccode\u003evalidate_form()\u003c/code\u003e function bypasses the intended database lookup and processes the attacker-controlled structure directly.
