Update summary
Fixes 1 CVE. Most severe CVSS 8.0 (High). EPSS exploit probability up to 2.2%. Among the top half of tracked Microsoft updates by EPSS exploit probability.
A newer security update for Microsoft SharePoint Server Subscription Edition has shipped since this one: KB5002927 (2026-10-13). 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.
KB5002800 patches CVE-2025-62204, a High severity flaw (CVSS 8.0) affecting SharePoint Enterprise Server 2016, SharePoint Server 2019, and SharePoint Server Subscription Edition. On-premises SharePoint farms are directly exposed, which matters because these servers often hold sensitive documents and are reachable from internal networks. Exploitation is not yet observed (EPSS 2%, not in CISA KEV), so this is a plan-and-patch situation rather than an emergency.
Do this: Schedule this November 2025 SharePoint update across all on-premises 2016, 2019, and Subscription Edition farms during your next maintenance window.
