{"id":"CVE-2026-17196","aliases":[],"url":"https://o3.security/vulnerability/CVE-2026-17196","summary":"The Super Forms – Drag & Drop Form Builder plugin for WordPress is vulnerable to Unrestricted File Type Upload in all versions up to, and including, 6.3.316 via the upload_files function.…","details":"The Super Forms – Drag & Drop Form Builder plugin for WordPress is vulnerable to Unrestricted File Type Upload in all versions up to, and including, 6.3.316 via the upload_files function. This is due to missing file type validation in the upload_files function, which reads and applies an attacker-controlled extensions string from _super_elements post meta verbatim as the allowed MIME type map. This makes it possible for authenticated attackers, with Subscriber-level access and above, to upload files that may be executable, which makes remote code execution possible. The attack requires a preceding step: poisoning the _super_elements post meta via the super_save_form AJAX handler, which lacks a capability and nonce check but requires the attacker to be authenticated as at minimum a Subscriber-level user; the subsequent file upload via super_upload_files requires no authentication at all.","published":"2026-10-08T05:17:04.657","modified":"2026-10-08T05:17:04.657","cvss":{"score":8.8,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/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":"WEB","url":"https://github.com/RensTillmann/super-forms/pull/205"},{"type":"WEB","url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/63db136b-58da-4758-a506-4dc79b3c177d?source=cve"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-10-08T05:17:04.657"}}
