Update summary
Fixes 1 CVE. Most severe CVSS 7.8 (High). EPSS exploit probability up to <1%. Among the lower half of tracked Microsoft updates by EPSS exploit probability.
A newer security update for Office Online Server has shipped since this one: KB5002884 (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.
KB5002716 patches CVE-2025-30379, a High severity (CVSS 7.8) flaw affecting Office Online Server and both 32-bit and 64-bit editions of Office 2019. The 7.8 score with no KEV listing and 0 percent EPSS points to a local exploitation path rather than remote drive-by, but the shared code base across desktop Office and the server product means server administrators cannot assume this is a workstation-only concern.
Do this: Deploy KB5002716 to Office 2019 clients and any Office Online Server instances, prioritizing the server tier since it is not on a normal desktop patch ring.
