This is due to the plugin dynamically granting the unfiltered_upload capability to all users during form submissions and bypassing MIME type validation when allowed_file_types is not configured. This makes it possible for unauthenticated attackers to execute code on the server. Several default pre-built templates including Job Application, Support Ticket, and Wholesale Application have file upload fields with no file type restrictions configured by design, making this vulnerability immediately exploitable upon installation.","state":"PUBLISHED","assigner":"Wordfence","published_at":"2026-08-29 12:16:41","updated_at":"2026-08-29 12:16:41"},"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://feedback.bdthemes.com/announcements","name":"https://feedback.bdthemes.com/announcements","refsource":"security@wordfence.com","tags":[],"title":"","mime":"","httpstatus":"","archivestatus":"0"},{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/44d63454-87f0-49e3-ac04-2fa83882500d?source=cve","name":"https://www.wordfence.com/threat-intel/vulnerabilities/id/44d63454-87f0-49e3-ac04-2fa83882500d?source=cve","refsource":"security@wordfence.com","tags":[],"title":"","mime":"","httpstatus":"","archivestatus":"0"},{"url":"https://www.cve.org/CVERecord?id=CVE-2026-14494","name":"CVE Program record","refsource":"CVE.ORG","tags":["canonical"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-14494","name":"NVD vulnerability detail","refsource":"NVD","tags":["canonical","analysis"]}],"affected":[{"source":"CNA","vendor":"bdthemes","product":"SigmaForms Pro – AI Generated Forms","version":"affected 1.4.5 semver","platforms":[]}],"timeline":[{"source":"CNA","time":"2026-07-02T18:05:03.000Z","lang":"en","value":"Vendor Notified"},{"source":"CNA","time":"2026-08-28T00:00:00.000Z","lang":"en","value":"Disclosed"}],"solutions":[],"workarounds":[],"exploits":[],"credits":[{"source":"CNA","value":"d.v4n_s3c","lang":"en"}],"nvd_cpes":[],"vendor_comments":[],"enrichments":{"kev":null,"epss":null,"legacy_qids":[]},"source_records":{"cve_program":{"containers":{"cna":{"affected":[{"defaultStatus":"unaffected","product":"SigmaForms Pro – AI Generated Forms","vendor":"bdthemes","versions":[{"lessThanOrEqual":"1.4.5","status":"affected","version":"0","versionType":"semver"}]}],"credits":[{"lang":"en","type":"finder","value":"d.v4n_s3c"}],"descriptions":[{"lang":"en","value":"The Sigma Forms Pro plugin for WordPress is vulnerable to Remote Code Execution in all versions up to, and including, 1.4.5 via the handle_form_submission function.
