In the absence of a patch, or until it can be applied, users can employ a Web Application Firewall (WAF) or Intrusion Detection System (IDS) as temporary mitigation to monitor network traffic and block any suspicious activity that might indicate an <a href=\"https:\/\/www.ameeba.com\/blog\/cve-2025-1740-excessive-authentication-attempts-vulnerability-in-akinsoft-myrezzta\/\"  data-wpil-monitor-id=\"86718\">attempt to exploit this vulnerability<\/a>.
