{"id":"CVE-2025-6679","state":"PUBLISHED","title":"Contact Form by Bit Form - Bit Form <= 2.20.3 - Unauthenticated Arbitrary File Upload","description":"The Bit Form builder plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in all versions up to, and including, 2.20.4. This makes it possible for unauthenticated attackers to upload arbitrary files on the affected site's server which may make remote code execution possible. For this to be exploitable, the PRO version needs to be installed and activated as well. Additionally a form with an advanced file upload element needs to be published.","publishedAt":"2025-08-15T06:40:42.601Z","updatedAt":"2026-04-08T16:59:38.425Z","severity":{"score":9.8,"label":"Critical","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","source":"Wordfence"},"assigner":"Wordfence","products":["bitpressadmin Bit Form – Custom Contact Form, Multi Step, Conversational Form & Payment Form builder"],"affected":[{"vendor":"bitpressadmin","product":"Bit Form – Custom Contact Form, Multi Step, Conversational Form & Payment Form builder","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"2.20.3","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/6e2e294f-904b-4674-8baf-d3a9a260d634?source=cve","https://wordpress.org/plugins/bit-form/","https://plugins.trac.wordpress.org/changeset?sfp_email=&sfph_mail=&reponame=&new=3343461%40bit-form%2Ftrunk&old=3336733%40bit-form%2Ftrunk&sfp_email=&sfph_mail="],"weaknesses":["CWE-434"],"ingestedAt":"2026-10-29T20:10:04.440Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2025/6xxx/CVE-2025-6679.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2025-6679","state":"PUBLISHED","datePublished":"2025-08-15T06:40:42.601Z","dateUpdated":"2026-04-08T16:59:38.425Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2025-06-25T19:36:25.214Z"},"containers":{"cna":{"title":"Contact Form by Bit Form - Bit Form <= 2.20.3 - Unauthenticated Arbitrary File Upload","descriptions":[{"lang":"en","value":"The Bit Form builder plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in all versions up to, and including, 2.20.4.
