KB5082060 is a large April 2026 rollup for Windows 10 1809 and Windows Server 2019 that closes 122 CVEs, topped by a Critical issue rated CVSS 9.8 with a 64 percent EPSS score. At least one of these CVEs is listed in the CISA Known Exploited Vulnerabilities catalog, meaning it is being exploited in the wild, though none are currently tied to ransomware. The combination of a confirmed exploited flaw plus a near-worst-case 9.8 bug on legacy Server 2019 infrastructure makes this a priority for domain-joined server fleets still on 1809.
Do this: Deploy KB5082060 to your Windows Server 2019 and Windows 10 1809 systems now, prioritizing the internet-facing and domain controller hosts affected by the CISA KEV-listed CVE.
