Emergency Patch for FortiClient EMS Zero-Day Exploit
⚠️ Fortinet released an emergency weekend hotfix to address a critical pre-authentication flaw in FortiClient EMS (CVE-2026-35616) that is being actively exploited in the wild. The improper access control defect allows unauthenticated attackers to execute commands via specially crafted API requests and affects versions 7.4.5 and 7.4.6. Fortinet urges immediate installation of the hotfixes or upgrading to 7.4.7 when available. Shadowserver reports over 2,000 exposed EMS instances, primarily in the US and Germany.
