{"schemaVersion":3,"id":"CVE-2026-14494","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"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. 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.","dates":{"published":"2026-08-29T11:30:17.164Z","modified":"2026-08-31T18:53:13.895Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":9.8,"severity":"critical","version":"3.1","versionLabel":"v3.1","source":"CVE.org","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","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","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"NVD","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","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"wordfence","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","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.00693,"percentile":0.52292,"severity":"low","asOf":"2026-10-21T00:00:00.000Z","change":{"pp":0,"baselineDate":"2026-09-21T00:00:00.000Z","baselineScore":0.00693},"history":[{"date":"2026-09-14T00:00:00.000Z","score":0.00693,"percentile":null},{"date":"2026-09-15T00:00:00.000Z","score":0.00693,"percentile":null},{"date":"2026-09-16T00:00:00.000Z","score":0.00693,"percentile":null},{"date":"2026-09-17T00:00:00.000Z","score":0.00693,"percentile":null},{"date":"2026-09-18T00:00:00.000Z","score":0.00693,"percentile":null},{"date":"2026-09-19T00:00:00.000Z","score":0.00693,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.00693,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.00693,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00693,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00693,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00693,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00693,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00693,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00693,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00693,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00693,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00693,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00693,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00693,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00693,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00693,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00693,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00693,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00693,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00693,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00693,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.00693,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.00693,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.00693,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.00693,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.00693,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00693,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00693,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00693,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00693,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00693,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.00693,"percentile":null},{"date":"2026-10-21T00:00:00.000Z","score":0.00693,"percentile":0.52292}],"last30":[{"date":"2026-09-21T00:00:00.000Z","score":0.00693,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00693,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00693,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00693,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00693,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00693,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00693,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00693,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00693,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00693,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00693,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00693,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00693,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00693,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00693,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00693,"percentile":null},{"date":"2026-10-07T00:00:00.000Z
