Technical details

The copy_file function in Groundhogg lacks sufficient file path validation, allowing authenticated attackers with the import_contacts capability to specify arbitrary file paths for deletion. The vulnerability affects CSV imports, the REST API, and webhooks that invoke the copy_file function. The fix, implemented in version 4.9.4, restricts file operations to the uploads directory and validates copyable URLs through a new is_copyable_url() check.
