The active exploitation of this zero-day before a patch was available shows that even security vendors' products are not immune to critical flaws. Organizations relying on FortiClient must treat this as a critical infrastructure component requiring immediate attention and robust patch management processes.","**Immediate actions:**\n- Apply the emergency patch for CVE-2026-35616 to all FortiClient installations immediately\n- Conduct emergency inventory of all Fortinet products in the environment to identify affected systems\n- Monitor network traffic for signs of authentication bypass attempts on FortiClient systems\n\n**Long-term improvements:**\n- Establish emergency patching procedures with defined timelines for critical security infrastructure\n- Implement automated vulnerability scanning specifically targeting security appliances and endpoint tools\n- Create network segmentation to limit exposure if security tools themselves are compromised\n\n**Detection measures:**\n- Enable comprehensive logging on all FortiClient systems to detect unauthorized access attempts\n- Set up automated alerts for authentication anomalies on systems protected by FortiClient",[12,13,14,15,16],"CIS Control 7 (Continuous Vulnerability Management)","NIST SP 800-40 (Patch Management)","NIST SP 800-53 SI-2 (Flaw Remediation)","CIS Control 1 (Inventory and Control of Enterprise Assets)","CIS Control 12 (Network Infrastructure Management)","published","2026-04-06T22:09:41.362311+00:00","2026-04-06T22:09:41.262+00:00",{"id":7,"url":21,"slug":22,"title":23},"https:\u002F\u002Fwww.darkreading.com\u002Fvulnerabilities-threats\u002Ffortinet-emergency-patch-forticlient-zero-day","fortinet-issues-emergency-patch-for-forticlient-zero-day","Fortinet Issues Emergency Patch for FortiClient Zero-Day",[25,31],{"id":26,"name":27,"slug":28,"description":29,"color":30},"05757c8d-6b93-4194-b35d-7359e7d33b0e","Vulnerability Management","vulnerability-management","Missing scans, no risk prioritization","#fb923c",{"id":32,"name":33,"slug":34,"description":35,"color":36},"af7fce9e-1ce8-4156-93bc-09dcfbfdf29d","Patch Management","patch-management","Unpatched vulnerabilities, delayed updates","#ef4444",[]]
