{"id":"CVE-2026-17196","published":"2026-10-08T05:17:04.657","lastModified":"2026-10-08T18:17:28.443","description":"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.","cvssScore":8.8,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","cwes":["CWE-434"],"vendors":[],"products":[],"references":[{"url":"https://github.com/RensTillmann/super-forms/pull/205","tags":[]},{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/63db136b-58da-4758-a506-4dc79b3c177d?source=cve","tags":[]}],"exploitRefs":[{"url":"https://github.com/RensTillmann/super-forms/pull/205","tags":[]}],"hasPoc":true,"ai":{"summary":"The flaw allows authenticated attackers to upload executable files, leading to remote code execution, due to missing file type validation.","exploitability":"Exploitation requires first poisoning the _super_elements post meta via the super_save_form AJAX handler, followed by an unauthenticated file upload. The attack is moderately complex due to the need for initial authentication and the specific handling of the super_save_form endpoint.","blast_radius":"If exploited, the vulnerability could lead to full control of the affected WordPress site, including remote code execution and potential data exfiltration.","remediation":"Disable the Super Forms – Drag & Drop Form Builder plugin until a patch is available, or upgrade to version 6.3.317 or later.","detection":"No reliable host or network indicator is derivable from the published description.","tags":["rce","web","wp-plugin","auth-bypass"],"model":"qwen2.5:7b-instruct","analyzedAt":"2026-10-09T08:43:52.214Z"}}
