Senserva AI Opinion for CVE-2025-49712

CVE-2025-49712 is a High severity (CVSS 8.8) remote code execution flaw in on-premises SharePoint Enterprise Server 2016 and SharePoint Server 2019, so any organization still running these self-hosted farms is exposed. It is not yet in CISA KEV and has no confirmed ransomware use, but the 18% EPSS score is notably elevated for an unexploited bug, and SharePoint RCE vulnerabilities have a history of being weaponized quickly once patches reveal the code path.

Do this: Apply the current Microsoft security update to your SharePoint 2016 and 2019 servers and review web application logs for unexpected requests to server pages.
