Senserva AI Opinion for CVE-2025-54906
This Office remote code execution flaw stands out from the batch because SharePoint Enterprise Server 2016 and SharePoint Server 2019 are on the affected list, and its 18 percent EPSS score is well above the neighboring Office bugs. A crafted document processed by SharePoint's server-side Office components can compromise the farm itself, not just one workstation. Severity is High at CVSS 8.8, and on-premises SharePoint remains a favorite target for attackers.
Do this: Patch on-premises SharePoint 2016 and 2019 servers ahead of desktop Office clients this cycle.
