CVE-2022-4101Public exploitNetwork attack vector

Unauthenticated file deletion via unchecked AJAX path

Published Jan 16, 2023 · Updated Apr 4, 2025

Path traversal in Images Optimize and Upload CF7 2.1.4 and earlier allows remote attackers to delete arbitrary server files via AJAX. The yr_api_delete action accepts an attacker-controlled file parameter without restricting the resolved path to the upload directory. No authentication is required; deletion of WordPress configuration or application files can interrupt the site or enable follow-on compromise.
