description

Ultra Addons for Contact Form 7 through version 3.5.54 has a path-validation flaw that can let unauthenticated attackers delete files on the server. Exploitation requires the PDF Generator add-on to be enabled and a Contact Form 7 form configured for PDF generation; deletion of certain files may allow subsequent code execution.

mitigation

Disable the PDF Generator feature and remove or deactivate the affected plugin until an updated release is available. Review affected sites for unexpected file deletions and restore protected configuration files from known-good backups if needed.
