{"id":"CVE-2026-15897","state":"PUBLISHED","title":"Super Forms – Drag & Drop Form Builder <= 6.3.316 - Authenticated (Subscriber+) Privilege Escalation via 'user_id' Parameter in Register & Login","description":"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.","publishedAt":"2026-10-02T05:30:17.190Z","updatedAt":"2026-10-03T15:42:50.803Z","severity":{"score":8.8,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","source":"Wordfence"},"assigner":"Wordfence","products":["WebRehab Super Forms – Drag & Drop Form Builder"],"affected":[{"vendor":"WebRehab","product":"Super Forms – Drag & Drop Form Builder","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"6.3.316","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/94297481-9ebb-42cb-9362-be8bc52b126f?source=cve","https://github.com/RensTillmann/super-forms/pull/205"],"weaknesses":["CWE-269"],"ingestedAt":"2026-10-29T20:11:00.674Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/15xxx/CVE-2026-15897.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-15897","state":"PUBLISHED","datePublished":"2026-10-02T05:30:17.190Z","dateUpdated":"2026-10-03T15:42:50.803Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-07-15T18:15:21.788Z"},"containers":{"cna":{"title":"Super Forms – Drag & Drop Form Builder <= 6.3.316 - Authenticated (Subscriber+) Privilege Escalation via 'user_id' Parameter in Register & Login","descriptions":[{"lang":"en","value":"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.
