Risk summary
Senserva AI Opinion for CVE-2025-54898
This Excel remote code execution flaw reaches beyond the desktop: Office Online Server is affected alongside Office 2019, so a server that renders spreadsheets in the browser can be hit by a single malicious workbook. Severity is High at CVSS 7.8, and with EPSS at 1 percent and no CISA KEV listing, this is a routine patch rather than an emergency. Organizations still running on-premises Office Online Server for SharePoint or Exchange document previews carry the most exposure.
Do this: Patch Office Online Server farms first, then push the Office 2019 update through your normal deployment ring.
