Title
Smart Popup by Supsystic <= 1.12.0 - Unauthenticated Privilege Escalation to Administrator
Summary
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.
