Update the Contact Form by Supsystic plugin to version 1.11.1 or later, where this vulnerability is fixed. No other mitigation is required as the fix properly sandboxes the template engine to prevent code injection.
Description
The Contact Form by Supsystic WordPress plugin before version 1.11.1 contains a server-side template injection vulnerability. This flaw allows an administrator to inject and execute arbitrary code on the server via the form template engine. The injected code executes whenever a visitor loads a page with the vulnerable form, enabling unauthenticated visitors to potentially read sensitive server-side information such as authentication salts and database credentials.
