Senserva AI Opinion for CVE-2026-32197

A Microsoft Excel remote code execution flaw that reaches Office Online Server as well as Office 2019 desktop installs, rated High Severity at CVSS 7.8. The EPSS exploitation probability is effectively zero right now, so this is a routine-cycle patch rather than an emergency. The Office Online Server angle matters because a malicious spreadsheet rendered server-side can compromise shared infrastructure, not just one desktop.

Do this: Include Office Online Server in the Office 2019 patch pass instead of treating this as desktop-only.
