European organizations should immediately verify their FreeScout deployment version and upgrade to version 1.8.180 or later where this vulnerability is patched. If upgrading is not immediately feasible, organizations should restrict access to FreeScout instances to trusted networks and enforce strict authentication and authorization controls to limit user privileges.
