After a long wait time, Microsoft finally released the new cumulative update KB4598242 for both Windows 10 v20H2 and v2004 users. This new update includes some fixes and improvements. However, the main focus of the update is to fix some security issues. Mainly, Microsoft fixed a vulnerability in HTTPS-based intranet servers. In addition to that, the update also fixes security bypass vulnerability in Printer Remote Procedure Call (RPC) binding and provides general security improvements for various Windows components like Windows media, Windows app framework, Hybrid storage systems, virtualization, etc.

All in all, the update is pretty eventful and we would recommend you install the update as soon as possible to fix the security issues.

KB4598242 Changelog

  • Addresses a security vulnerability issue with HTTPS-based intranet servers. After installing this update, HTTPS-based intranet servers cannot, by default, use a user proxy to detect updates. Scans using these servers will fail if you have not configured a system proxy on the clients. If you must use a user proxy, you must configure the behavior using the policy “Allow user proxy to be used as a fallback if detection using system proxy fails.” To ensure the highest levels of security, also use Windows Server Update Services (WSUS) Transport Layer Security (TLS) certificate pinning on all devices. This change does not affect customers who are using HTTP WSUS servers. For more information, see Changes to scans, improved security for Windows devices.
  • Addresses a security bypass vulnerability that exists in the way the Printer Remote Procedure Call (RPC) binding handles authentication for the remote Winspool interface. For more information, see KB4599464.
  • Security updates to Windows App Platform and Frameworks, Windows Media, Windows Fundamentals, Windows Kernel, Windows Cryptography, Windows Virtualization, Windows Peripherals, and Windows Hybrid Storage Services.

That is it.
