This makes it possible for unauthenticated attackers to set the `original_user_id` cookie to any administrator's user ID, collect the rendered nonce, and POST it back to the `revert_switch` handler, causing `wp_set_auth_cookie()` to be called with the administrator's ID and granting the attacker a full administrator-level authenticated session and complete site takeover.","published":"2026-10-02T04:18:06.277","modified":"2026-10-02T04:18:06.277","cvss":{"score":9.8,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://docs.dplugins.com/devkit/changelog"},{"type":"WEB","url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/2ab3986a-69e0-442f-8e79-35b1bc5376d9?source=cve"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-10-02T04:18:06.277"}}
