KB5058449: Windows Server 2019 Security Update (May 2025)
KB5058449 is a High security update for Windows Server 2019, released 2025-05-13. It closes 23 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-2025-29959, which FIRST.org rates at 61% probability of exploitation in the next 30 days.
Update summary
Fixes 23 CVEs. At least one is actively exploited (CISA KEV). Most severe CVSS 8.8 (High). EPSS exploit probability up to 21%. Among the top half 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.
KB5058449 is May 2025's update for Windows 10 1809 and Windows Server 2019, resolving 23 CVEs with a High, CVSS 8.8 top severity, 22 percent EPSS, and a CISA KEV-listed flaw among them. This predates the June update family covered elsewhere, so both months need to land in order on any server that skipped May. The 22 percent EPSS score keeps this above routine-priority patching.
Do this: Confirm KB5058449 is installed ahead of the June 2025 updates on any Windows 10 1809 or Server 2019 host that has fallen behind.
