{"id":"CVE-2026-104797","published":"2026-10-10T04:18:08.677","lastModified":"2026-10-13T13:30:21.620","description":"The Advanced Form Integration — Connect Forms to 300+ Apps plugin for WordPress is vulnerable to Authentication Bypass via Unverified Password Change in all versions up to, and including, 2.9.0 The `adfoin_ultimatememberac_send_data` function, which powers the Ultimate Member \"Update Profile Field\" action, resolves the target WordPress user from an attacker-supplied email address and passes an attacker-controlled field key and value directly to `UM()->user()->update_profile()` in the `account` context — which explicitly bypasses Ultimate Member's banned-key validation — without performing any submitter identity verification, ownership check, capability check, current-password reauthentication, or restriction on sensitive keys such as `user_pass`. 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.","cvssScore":8.1,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","cwes":["CWE-287"],"vendors":[],"products":[],"references":[{"url":"https://plugins.trac.wordpress.org/browser/advanced-form-integration/","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/advanced-form-integration/tags/2.9.0/includes/triggers/cf7/cf7.php#L38","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/advanced-form-integration/tags/2.9.0/platforms/ultimatememberac/ultimatememberac.php#L169","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/advanced-form-integration/tags/2.9.0/platforms/ultimatememberac/ultimatememberac.php#L83","tags":[]},{"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","tags":[]},{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/586fd95e-88c7-4eb8-826c-ae46a11ac21f?source=cve","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":{"summary":"The plugin allows unauthenticated attackers to bypass authentication and change any WordPress user's password by exploiting a vulnerable function that updates Ultimate Member profile fields without verifying the submitter's identity or checking user permissions.
