{"id":"CVE-2026-15989","aliases":[],"url":"https://o3.security/vulnerability/CVE-2026-15989","summary":"Super Forms <= 6.3.316 - Unauthenticated Privilege Escalation via 'role' Parameter","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 whitelisting the client-submitted 'role' key and copying it into the user-data array that is passed directly to wp_insert_user(), without validating the submitted role against the administrator-configured register_user_role, without an allow-list, and without any current_user_can() capability check. This makes it possible for unauthenticated attackers to register a new account with the Administrator role by injecting role=administrator into the data submitted to any published Super Forms registration form (register_login_action='register').","published":"2026-10-01T07:40:23.893Z","modified":"2026-10-02T03:47:34.971312113Z","cvss":{"score":9.8,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/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":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/15xxx/CVE-2026-15989.json"},{"type":"FIX","url":"https://github.com/RensTillmann/super-forms/pull/205"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-15989"},{"type":"WEB","url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/7eb62d35-3f0e-4733-8f7f-723d0f25b710?source=cve"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-10-02T03:47:34.971312113Z"}}
