This is due to the Register \u0026 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.","severity":{"version":"3.1","score":8.8,"vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","level":"high","assessor":"cna","from":"cve"},"epss":{"day":"2026-11-11","score":0.00294,"percentile":0.22312,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":false,"fix_available":false},"cwes":["CWE-269"],"published":"2026-10-02T05:30:17Z","modified":"2026-10-28T02:31:10Z","products":[{"vendor":"webrehab","product":"super forms – drag \u0026 drop form builder"}],"references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/94297481-9ebb-42cb-9362-be8bc52b126f?source=cve","tags":["web"]},{"url":"https://github.com/RensTillmann/super-forms/pull/205","tags":["fix"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-15897","tags":["advisory"]},{"url":"https://github.com/advisories/GHSA-h8h9-7p7r-7rpq"},{"url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/15xxx/CVE-2026-15897.json","tags":["advisory"]}],"sources":{"cve":[{"id":"CVE-2026-15897","title":"Super Forms – Drag \u0026 Drop Form Builder \u003c= 6.3.316 - Authenticated (Subscriber+) Privilege Escalation via 'user_id' Parameter in Register \u0026 Login","description":"The Super Forms – Drag \u0026 Drop Form Builder plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 6.3.316.
