This is due to the Register & Login add-on's before_email_success_msg() function, in its register_login_action='update' flow, trusting an attacker-supplied user_id value and passing it to wp_update_user() without any ownership or capability check. Because the super_save_form AJAX action also enforces no capability check, any authenticated user with Subscriber-level access and above can create the required malicious form (register_login_action='update' with register_login_user_id_update='true') and then submit it with user_id set to an administrator's ID along with a new user_pass/user_email. This makes it possible for authenticated attackers with Subscriber-level access and above to overwrite the credentials of arbitrary existing accounts — including administrators — resulting in account takeover and full site compromise.","published":"2026-10-02T06:16:41.053","modified":"2026-10-02T06:16:41.053","cvss":{"score":8.8,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":{"url":"https://github.com/RensTillmann/super-forms/pull/205","label":"RensTillmann/super-forms#205"},"references":[{"type":"WEB","url":"https://github.com/RensTillmann/super-forms/pull/205"},{"type":"WEB","url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/94297481-9ebb-42cb-9362-be8bc52b126f?source=cve"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-10-02T06:16:41.053"}}
