Microsoft’s June 2026 Patch Tuesday is the largest in the program’s 23-year history, delivering 206 CVEs including two unauthenticated CVSS 9.5 RCEs in core Windows networking components that expose every internet-facing Windows server without requiring credentials or user interaction. Three CVEs were publicly disclosed before patches were available, including a BitLocker bypass with active proof-of-concept code, elevating this cycle to emergency status for any organization running internet-exposed Windows Server infrastructure.
