{"schema":"threatline.record/2","record":{"id":"CVE-2026-15897","aliases":[],"summary":"Super Forms – Drag & Drop Form Builder <= 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.","categories":["Unclassified"],"product":"Super Forms – Drag & Drop Form Builder","vendor":"WebRehab","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-15897","source_modified_at":"2026-10-03T15:42:50.803Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"Super Forms – Drag & Drop Form Builder","vendor":"WebRehab","versions":[{"version":"0","status":"affected","lessThanOrEqual":"6.3.316","versionType":"semver"}],"defaultStatus":"unaffected"}],"fixed_versions":[],"cvss":8.8,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00303,"percentile":0.21906,"score_date":"2026-10-23"},"published_at":"2026-10-02T05:30:17.190Z","modified_at":"2026-10-03T15:42:50.803Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-15897","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-10-03T15:42:50.803Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-15897","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/94297481-9ebb-42cb-9362-be8bc52b126f?source=cve"},{"source":"CVE List","url":"https://github.com/RensTillmann/super-forms/pull/205"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"total","assessed_at":"2026-10-03T15:30:29.754309Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-03T15:42:50.803Z","content_hash":"31e75773fc13d6b8a3488f1d696c33106ff088ba508fdda58a74e9759d45c6f4"}}
