Senserva AI Opinion for CVE-2025-29820

Like its sibling Word flaw in this set, this remote code execution bug reaches SharePoint Enterprise Server 2016 as well as Office 2019 desktops, and its CVSS of 8.8 and 16 percent EPSS put it near the top of the document-bug pile. Server-side Word parsing means an uploaded file can be enough, no user click required.

Do this: Update SharePoint 2016 farms first, then sweep Office 2019 desktops in the same cycle.
