Update summary
Fixes 55 CVEs. Most severe CVSS 9.8 (Critical). EPSS exploit probability up to 41%. Among the top 25% of tracked Microsoft updates by EPSS exploit probability.
A newer security update for Windows Server 2008 R2 for x64-based Systems Service Pack 1 has shipped since this one: KB5073695 (2026-01-13). For cumulative update families the newer package includes these fixes, so installing that one is usually the shorter path. Verify against your own update rings before you skip this package.
KB5062619 is the August 12, 2025 rollup for Windows 10 1809 and Windows Server 2019, closing 55 CVEs including one rated Critical at CVSS 9.8. None are on the CISA KEV list or tied to ransomware yet, and the highest EPSS is 22 percent, so this is a large preventive batch rather than a fix for active attacks. Windows Server 2019 fleets are most exposed here since the 9.8 remote code execution class of flaw is most dangerous on internet-reachable or lateral-movement-prone servers.
Do this: Deploy KB5062619 to your Windows Server 2019 hosts first, then roll it out to remaining Windows 10 1809 systems in your next patch window.
