March 2026 CVE Landscape: 31 High-Impact Vulnerabilities Identified, Interlock Ransomware Group Exploits Cisco FMC Zero-Day

Insikt Group identified 31 high-impact vulnerabilities actively exploited in March 2026, with 29 rated as very critical. The affected products span major vendors including Cisco, Microsoft, Google, ConnectWise, Citrix, and others, with Microsoft and Apple accounting for approximately 32% of the total. Notable findings include the Interlock ransomware group exploiting a Cisco Firewall Management Center zero-day, the continued exploitation of a nine-year-old Hikvision vulnerability, and public proof-of-concept exploits available for 10 of the 31 vulnerabilities.

Why it matters: Security teams must prioritize remediation of these 31 actively exploited vulnerabilities immediately, with special attention to Cisco FMC, Microsoft SQL Server, and products from other affected vendors; legacy systems with known, unpatched vulnerabilities remain high-risk targets and require compensating controls or urgent patching.
