However, as a temporary measure, you can also use a Web Application Firewall (WAF) or Intrusion Detection System (IDS) to monitor and block suspicious traffic. Regular patching and updating of systems as well as monitoring <a href=\"https:\/\/www.ameeba.com\/blog\/cve-2025-31214-a-critical-network-traffic-interception-vulnerability-in-ios-and-ipados\/\"  data-wpil-monitor-id=\"55150\">network traffic<\/a> for anomalies are also recommended best practices.<br \/>\nIn conclusion, the CVE-2025-46633 <a href=\"https:\/\/www.ameeba.com\/blog\/cve-2025-43922-unprivileged-local-user-privilege-escalation-vulnerability-in-filewave-windows-client\/\"  data-wpil-monitor-id=\"41436\">vulnerability represents a significant security threat to users<\/a> of the affected product.
