KB5002788: Microsoft SharePoint Server 2019 Security Update (October 2025)
KB5002788 is a High security update for Microsoft SharePoint Server 2019, released 2025-10-14. It closes 6 CVEs with a maximum CVSS of 8.8. It is the 17th largest of the 60 updates Microsoft shipped that month, by CVEs closed.
Update summary
Fixes 6 CVEs. Most severe CVSS 8.8 (High). EPSS exploit probability up to 2.3%. Among the lower half of tracked Microsoft updates by EPSS exploit probability.
A newer security update for Microsoft SharePoint Enterprise Server 2016 has shipped since this one: KB5002882 (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.
KB5002788 patches 6 CVEs across SharePoint Server 2016, 2019, and Subscription Edition, with the worst rated High severity at CVSS 8.8. On-premises SharePoint farms are exposed, but none of these CVEs are in CISA KEV and EPSS tops out at only 2 percent, so active exploitation is not currently indicated. The CVSS 8.8 rating still means an authenticated user could likely escalate to code execution on the server, which matters given SharePoint's central role.
Do this: Schedule this SharePoint server-side update across all 2016, 2019, and Subscription Edition farms during your next patch window, prioritizing internet-reachable servers.
