Risk summary
Not in the CISA KEV catalog. EPSS exploit probability 14%. CVSS 7.8 (High).
This CVE is among the lower half of tracked Microsoft CVEs by EPSS exploit probability.
This is a DWM Core Library elevation of privilege flaw in the Windows desktop compositor, carrying High severity at CVSS 8.8 and confined to Windows 10 Version 1809 (32-bit and x64) and Windows Server 2019. Exposure is narrow to these older builds, but the CVSS 8.8 rating implies a local attacker with a foothold can gain higher privileges, which turns any low-privilege compromise into a full takeover path. It is not in CISA KEV and has no known ransomware use, and the 13% EPSS puts it above most CVEs for near-term exploit likelihood without being confirmed in the wild.
Do this: Apply the Microsoft patch to your Windows 10 1809 and Windows Server 2019 hosts, prioritizing servers and multi-user or shared systems where local footholds are most dangerous.
