{"id":"CVE-2026-107652","state":"PUBLISHED","title":"Database Addon for Contact Form 7 <= 1.4.1 - Unauthenticated Limited File Deletion via Injected 'attackcfdb7_file' Submission Field","description":"The Database Addon for Contact Form 7 – CFDB7 plugin for WordPress is vulnerable to Arbitrary File Deletion in versions up to, and including, 1.4.1. This is due to the plugin storing arbitrary (non-form-tag) submission fields in its db7_forms row and the process_bulk_action() delete handler then matching any stored key whose name contains the substring 'cfdb7_file' and passing the stored value directly to unlink() without validating that the file actually belongs to the submission being deleted or constraining the filename with basename()/realpath(). This makes it possible for unauthenticated attackers to inject a crafted multipart field.","publishedAt":"2026-10-14T01:27:14.328Z","updatedAt":"2026-10-15T16:43:51.315Z","severity":{"score":5.3,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["arshidkv12 Database Addon for Contact Form 7 – CFDB7"],"affected":[{"vendor":"arshidkv12","product":"Database Addon for Contact Form 7 – CFDB7","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"1.4.1","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/7de3606a-254c-4e5f-9499-b1cc79dce7c8?source=cve","https://plugins.trac.wordpress.org/browser/contact-form-cfdb7/tags/1.4.0/inc/admin-subpage.php#L329","https://plugins.trac.wordpress.org/browser/contact-form-cfdb7/tags/1.4.0/inc/admin-subpage.php#L325","https://plugins.trac.wordpress.org/browser/contact-form-cfdb7/tags/1.4.0/contact-form-cfdb-7.php#L170","https://plugins.trac.wordpress.org/changeset?reponame=&old=3737068%40contact-form-cfdb7&new=3737068%40contact-form-cfdb7"],"weaknesses":["CWE-639"],"ingestedAt":"2026-10-29T20:10:23.711Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/107xxx/CVE-2026-107652.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-107652","state":"PUBLISHED","datePublished":"2026-10-14T01:27:14.328Z","dateUpdated":"2026-10-15T16:43:51.315Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-10-08T14:28:28.743Z"},"containers":{"cna":{"title":"Database Addon for Contact Form 7 <= 1.4.1 - Unauthenticated Limited File Deletion via Injected 'attackcfdb7_file' Submission Field","descriptions":[{"lang":"en","value":"The Database Addon for Contact Form 7 – CFDB7 plugin for WordPress is vulnerable to Arbitrary File Deletion in versions up to, and including, 1.4.1.
