Senserva AI Opinion for CVE-2025-49703

The 100 percent EPSS score on this Microsoft Word remote code execution flaw is the highest number in this entire release: exploitation attempts are expected with near certainty even though CISA has not yet confirmed in-the-wild use. SharePoint Enterprise Server 2016 and SharePoint Server 2019 are affected alongside Office 2019, so server-side document processing is in scope, not just desktops. Severity is High at CVSS 8.8.

Do this: Patch on-premises SharePoint 2016 and 2019 today, before anything else in this batch, then sweep Office 2019 clients.
