This is due to missing authorization checks on the twiz_ajax_callback AJAX action\u0027s \u0027savesection\u0027 handler combined with the use of eval() to execute user-supplied \u0027custom logic\u0027 code on the frontend. The AJAX handler at twiz-ajax.php verifies a nonce but performs no current_user_can() capability check for the ACTION_SAVE_SECTION case. Furthermore, the nonce is exposed to any authenticated user through the directly-accessible twiz-ajax.js.php file which loads WordPress and outputs the nonce. This makes it possible for authenticated attackers, with Subscriber-level access and above, to inject arbitrary PHP code via the twiz_custom_logic POST parameter when saving a section with output choice \u0027twiz_logic_output\u0027."
