{"id":"CVE-2026-15897","summary":"Super Forms – Drag & Drop Form Builder \u003c= 6.3.316 - Authenticated (Subscriber+) Privilege Escalation via 'user_id' Parameter in Register & Login","details":"The Super Forms – Drag & Drop Form Builder plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 6.3.316. 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.","modified":"2026-10-05T02:30:33.752691775Z","published":"2026-10-02T05:30:17.190Z","database_specific":{"cna_assigner":"Wordfence","cwe_ids":["CWE-269"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/15xxx/CVE-2026-15897.json"},"references":[{"type":"WEB","url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/94297481-9ebb-42cb-9362-be8bc52b126f?source=cve"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/15xxx/CVE-2026-15897.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-15897"},{"type":"FIX","url":"https://github.com/RensTillmann/super-forms/pull/205"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/renstillmann/super-forms","events":[{"introduced":"0"},{"last_affected":"1966e6baf333502f67574e1bcd0758f986709382"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"last_affected":"6.3.316"}],"source":"AFFECTED_FIELD"}}],"versions":["v6.3.316","v6.3.315","v6.3.314","v6.3.313"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-15897.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
