Senserva AI Opinion for CVE-2025-64672

A SharePoint spoofing flaw with an unusual scope: only SharePoint Server Subscription Edition is affected, sparing the older 2016 and 2019 farms for once. It is rated High Severity at CVSS 8.8 with a 1% EPSS. Subscription Edition shops chose that platform for its continuous update model, and this bug is the test of whether that model is actually being exercised on your farms.

Do this: Confirm Subscription Edition farms are current with the latest security update and that their update automation genuinely ran rather than silently failing.
