Senserva AI Opinion for CVE-2026-50694

This is a Remote Code Execution flaw in the Windows Secure Socket Tunneling Protocol (SSTP), the VPN transport used to tunnel PPP traffic over HTTPS. It carries a Severity rating of Critical with a CVSS score of 9.9, which suggests a low-privilege or unauthenticated path to code execution, and it affects Windows 10 Version 1809 and Windows Server 2019. Any server acting as an SSTP-based Remote Access (RRAS) VPN endpoint on these builds is the highest-value target here.

Do this: Patch affected Windows Server 2019 RRAS/SSTP VPN gateways and 1809 clients first, and restrict SSTP endpoint exposure to the public internet where the fix cannot be applied immediately.
