This makes it possible for unauthenticated attackers to change the password of any WordPress user account, including Administrator accounts, by submitting a public Contact Form 7 form with a target email and `user_pass` as the field key, enabling full site takeover. Exploitation requires an administrator to have pre-configured a Contact Form 7 integration that maps the target email, field key, and value from public form inputs to the Ultimate Member Update Profile Field action — the exact workflow the plugin's own UI advertises for this action type.","published":"2026-10-10T04:18:08.677","modified":"2026-10-10T04:18:08.677","cvss":{"score":8.1,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:H/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://plugins.trac.wordpress.org/browser/advanced-form-integration/"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/advanced-form-integration/tags/2.9.0/includes/triggers/cf7/cf7.php#L38"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/advanced-form-integration/tags/2.9.0/platforms/ultimatememberac/ultimatememberac.php#L169"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/advanced-form-integration/tags/2.9.0/platforms/ultimatememberac/ultimatememberac.php#L83"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/changeset?reponame=&new=3725787%40advanced-form-integration%2Ftags%2F2.10.0&old=3707004%40advanced-form-integration%2Ftags%2F2.9.0"},{"type":"WEB","url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/586fd95e-88c7-4eb8-826c-ae46a11ac21f?source=cve"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-10-10T04:18:08.677"}}
