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.
This flaw is unusual for being tied to a specific kernel API, the NtQueryInformationToken function exposed through ntifs.h, on Windows 10 1809 and Windows Server 2019. Token-handling bugs go straight at Windows privilege boundaries, and this one is rated Critical at CVSS 9.9. EPSS forecasts 6 percent exploitation probability with nothing yet in the KEV catalog.
Do this: Schedule Server 2019 domain infrastructure for this update first, since token manipulation is central to lateral movement.
