This is due to a mismatch between the field validation pipeline and the file persistence pipeline, where hidden file upload fields bypass extension validation and a rejected file's intact upload state is later passed to upload_file() without re-validation. This makes it possible for unauthenticated attackers to upload files that may be executable, which makes remote code execution possible. Exploitation requires the targeted form to contain a File Upload field with its Visibility set to 'Hidden'; the vulnerability is reachable by unauthenticated attackers on any publicly accessible form meeting this condition.","state":"PUBLISHED","assigner":"Wordfence","published_at":"2026-09-19 03:17:15","updated_at":"2026-09-19 03:17:15"},"problem_types":["CWE-434","CWE-434 CWE-434 Unrestricted Upload of File with Dangerous Type"],"metrics":[{"version":"3.1","source":"security@wordfence.com","type":"Primary","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","data":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","baseScore":9.8,"baseSeverity":"CRITICAL","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"HIGH"}},{"version":"3.1","source":"CNA","type":"DECLARED","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","data":{"baseScore":9.8,"baseSeverity":"CRITICAL","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"}}],"references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/787e22a9-329b-4e71-bc2a-4f5524fc9356?source=cve","name":"https://www.wordfence.com/threat-intel/vulnerabilities/id/787e22a9-329b-4e71-bc2a-4f5524fc9356?source=cve","refsource":"security@wordfence.com","tags":[],"title":"","mime":"","httpstatus":"","archivestatus":"0"},{"url":"https://docs.gravityforms.com/gravityforms-change-log/","name":"https://docs.gravityforms.com/gravityforms-change-log/","refsource":"security@wordfence.com","tags":[],"title":"","mime":"","httpstatus":"","archivestatus":"0"},{"url":"https://www.cve.org/CVERecord?id=CVE-2026-84434","name":"CVE Program record","refsource":"CVE.ORG","tags":["canonical"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-84434","name":"NVD vulnerability detail","refsource":"NVD","tags":["canonical","analysis"]}],"affected":[{"source":"CNA","vendor":"Gravity Forms","product":"Gravity Forms","version":"affected 3.1.0.4 semver","platforms":[]}],"timeline":[{"source":"CNA","time":"2026-09-01T19:16:54.000Z","lang":"en","value":"Vendor Notified"},{"source":"CNA","time":"2026-09-18T13:56:54.000Z","lang":"en","value":"Disclosed"}],"solutions":[],"workarounds":[],"exploits":[],"credits":[{"source":"CNA","value":"0xd4rk5id3","lang":"en"}],"nvd_cpes":[],"vendor_comments":[],"enrichments":{"kev":null,"epss":null,"legacy_qids":[]},"source_records":{"cve_program":{"containers":{"cna":{"affected":[{"defaultStatus":"unaffected","product":"Gravity Forms","vendor":"Gravity Forms","versions":[{"lessThanOrEqual":"3.1.0.4","status":"affected","version":"0","versionType":"semver"}]}],"credits":[{"lang":"en","type":"finder","value":"0xd4rk5id3"}],"descriptions":[{"lang":"en","value":"The Gravity Forms plugin for WordPress is vulnerable to Arbitrary File Upload in all versions up to, and including, 3.1.0.4 via the upload_file function.
