CVE-2026-107652
CVE-2026-107652 · Database Addon for Contact Form 7 <= 1.4.1 - Unauthenticated Limited File Deletion via Injected 'attackcfdb7_file' Submission Field
This page contains facts from public vulnerability sources. Check the original advisory before updating.
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.
