Risk summary
Listed in the CISA Known Exploited Vulnerabilities catalog, confirmed exploited in the wild. EPSS exploit probability 71%. CVSS 4.3 (Medium).
This CVE is among the top 5% of tracked Microsoft CVEs by EPSS exploit probability, and one of 5 actively-exploited CVEs in July 2026.
A spoofing flaw in the Windows Shell rated Critical at CVSS 9.8, which is unusually high for a spoofing class bug and points to an attacker being able to misrepresent trusted content or origin on affected systems. Exposure is limited to Windows 10 Version 1809 (32-bit and x64) and Windows Server 2019, and it is already confirmed exploited in the wild by CISA KEV as of 2026-04-28 with a 64% EPSS score. The KEV listing plus the high exploit probability makes this an active threat rather than a theoretical one, even though no ransomware use is currently tied to it.
Do this: Identify every Windows 10 1809 and Windows Server 2019 host in your fleet and apply Microsoft's patch for CVE-2026-32202 immediately, prioritizing internet-facing and shared systems.
