Update summary
Fixes 6 CVEs. 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.
KB5002801 is the November 11, 2025 update patching 6 CVEs across Office 2019 (32-bit and 64-bit) and Office Online Server, with a highest severity of High at CVSS 7.8. The CVSS 7.8 rating points to local exploitation, typically requiring a user to open a crafted file, and the Office Online Server coverage means both desktop and server-side document rendering are in scope. None of these CVEs are in the CISA KEV catalog and EPSS peaks at only 1%, so there is no evidence of active exploitation yet.
Do this: Deploy KB5002801 to Office 2019 clients and Office Online Server hosts during your next patch window, prioritizing the server-side install since it processes documents from multiple users.
