"value": "The Smart Popup by Supsystic plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 1.12.0. This is due to a permission map collision in the `havePermissions()` function in `classes/frame.php`, where `array_merge()` overwrites the popup module's administrator-restricted method list with the base controller's value, silently removing `save` from protected actions; this is compounded by the subscription confirmation email embedding the same generic `pps_nonce` that the unauthenticated `wp_ajax_nopriv_save` endpoint accepts, and by the complete absence of any server-side role allowlist in `createWpSubscriber()`. This makes it possible for unauthenticated attackers to submit a crafted POST request to `admin-ajax.php` using a nonce obtained from a public subscription confirmation email, setting `params[tpl][sub_wp_create_user_role]` to `administrator` via the exposed `popupControllerPps::save()` action, and then triggering the stored confirmation flow to create a persistent WordPress Administrator account with attacker-chosen credentials."
