KB5061026: Windows Server 2019 Security Update (June 2025)
KB5061026 is a High security update for Windows Server 2019, released 2025-06-10. It closes 12 CVEs with a maximum CVSS of 8.8. At least one of them is actively exploited (CISA KEV), so this is a deploy-first update. The most likely of them to be attacked is CVE-2025-32712, which FIRST.org rates at 85% probability of exploitation in the next 30 days.
Update summary
Fixes 12 CVEs. At least one is actively exploited (CISA KEV). Most severe CVSS 8.8 (High). EPSS exploit probability up to 85%. Among the top 5% of tracked Microsoft updates by EPSS exploit probability.
A newer security update for Windows 10 Version 1809 for 32-bit Systems has shipped since this one: KB5094041 (2026-08-11). 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.
KB5061026 is a leaner June 2025 update for Windows 10 version 1809 and Windows Server 2019, fixing twelve CVEs that lean heavily on the newer CVE-2025-330xx family, including CVE-2025-33064, CVE-2025-33066, CVE-2025-33075, and CVE-2025-33053, rather than the larger set patched elsewhere this month. It still carries a High severity, CVSS 8.8 top rating with an 82 percent EPSS score and CISA KEV inclusion, so the smaller fix count is not a lighter weight update in risk terms. This looks like a targeted servicing package layered on the main June rollup.
Do this: Install KB5061026 in addition to the main June 2025 cumulative update, not as a substitute for it.
