  • 21 critical CVEs disclosed, up 91% from yesterday's 11
  • 67 high-priority vulnerabilities, down 6% from 71
  • 17 actively exploited CVEs including Cisco, Fortinet, SonicWall, and WinRAR
  • 0% patch availability requires compensating controls and enhanced monitoring
  • Affected systems include Android Framework, Microsoft Windows, GeoServer, and D-Link routers

Immediate action: Prioritize network segmentation and access controls for systems affected by actively exploited CVEs, particularly Cisco, Fortinet, and SonicWall appliances. With no patches currently available, implement detection rules for exploitation attempts and restrict exposure of vulnerable services. Thursday timing allows for assessment and control implementation before reduced weekend staffing.
