Risk summary
Not in the CISA KEV catalog. EPSS exploit probability 6.0%. CVSS 7.8 (High).
This CVE is among the lower half of tracked Microsoft CVEs by EPSS exploit probability.
The Desktop Window Manager keeps producing Critical findings, and this CVSS 9.9 elevation of privilege on Windows 10 1809 and Windows Server 2019 is another. Given the volume of DWM flaws being patched, assume exploit developers are studying the same code paths; the 6 percent EPSS score reflects prediction, not safety. Severity is Critical.
Do this: Do not defer this one on Server 2019 RDS hosts, where many interactive sessions make DWM a shared attack surface.
