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."}], "title": "Smart Popup by Supsystic <= 1.12.0 - Unauthenticated Privilege Escalation to Administrator", "references": [{"url": "https://www.wordfence.com/threat-intel/vulnerabilities/id/835579b0-8a96-40fa-a6a3-30571a0a1d0a?source=cve"}, {"url": "https://plugins.trac.wordpress.org/browser/popup-by-supsystic/tags/1.11.2/classes/frame.php#L180"}, {"url": "https://plugins.trac.wordpress.org/browser/popup-by-supsystic/tags/1.11.2/modules/subscribe/models/subscribe.php#L440"}, {"url": "https://plugins.trac.wordpress.org/browser/popup-by-supsystic/tags/1.11.2/modules/subscribe/models/subscribe.php#L292"}, {"url": "https://plugins.trac.wordpress.org/browser/popup-by-supsystic/tags/1.11.2/modules/popup/models/popup.php#L316"}, {"url": "https://plugins.trac.wordpress.org/browser/popup-by-supsystic/tags/1.11.2/modules/subscribe/models/subscribe.php#L358"}, {"url": "https://plugins.trac.wordpress.org/changeset?sfp_email=&sfph_mail=&reponame=&new=3629986%40popup-by-supsystic%2Ftrunk%2Fmodules%2Fsubscribe%2Fmodels%2Fsubscribe.php&old=3628131%40popup-by-supsystic%2Ftrunk%2Fmodules%2Fsubscribe%2Fmodels%2Fsubscribe.php&sfp_email=&sfph_mail="}], "problemTypes": [{"descriptions": [{"lang": "en", "description": "CWE-269 Improper Privilege Management", "cweId": "CWE-269", "type": "CWE"}]}], "metrics": [{"cvssV3_1": {"version": "3.1", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H", "baseScore": 8.8, "baseSeverity": "HIGH"}}], "credits": [{"lang": "en", "type": "finder", "value": "daroo"}], "timeline": [{"time": "2026-07-29T19:49:17.000Z", "lang": "en", "value": "Vendor Notified"}, {"time": "2026-08-04T16:04:04.000Z", "lang": "en", "value": "Disclosed"}]}}}
