KB5002719: Office Online Server Security Update (October 2025)
KB5002719 is a High security update for Office Online Server, released 2025-10-14. It closes 2 CVEs with a maximum CVSS of 7.1. It is the 26th largest of the 60 updates Microsoft shipped that month, by CVEs closed.
Update summary
Fixes 2 CVEs. Most severe CVSS 7.1 (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.
KB5002719 patches two CVEs in the SharePoint family, covering Office Online Server, SharePoint Enterprise Server 2016, and SharePoint Server 2019, with a top rating of High (CVSS 7.1). These are on-premises server products often internet-facing for collaboration, so any organization still running self-hosted SharePoint is exposed. Neither CVE is in CISA KEV or ransomware-linked, and EPSS peaks at only 1 percent, so this is a maintenance patch rather than an emergency.
Do this: Schedule this SharePoint update through your normal patch cycle, prioritizing any farm servers that are reachable from the internet.
