{"schema":"threatline.record/2","record":{"id":"CVE-2026-17196","aliases":[],"summary":"Super Forms <= 6.3.316 - Authenticated (Subscriber+) Arbitrary File Upload via 'extensions' Form Element Attribute","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.","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-2026-17196","source_modified_at":"2026-10-08T17:54:41.191Z","fetched_at":"2026-10-23T18:48:36.087640Z","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":0.00533,"percentile":0.44247,"score_date":"2026-10-23"},"published_at":"2026-10-08T04:28:51.005Z","modified_at":"2026-10-08T17:54:41.191Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-17196","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-08T17:54:41.191Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-17196","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/63db136b-58da-4758-a506-4dc79b3c177d?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":"2026-10-08T17:54:24.458370Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-08T17:54:41.191Z","content_hash":"2f8d3267611261819df36df139253a1e18472f5b63ca2aa5982f22af75a8902d"}}
