CVE-2025-49706 is a spoofing flaw in on-premises SharePoint (Enterprise Server 2016, Server 2019, and Subscription Edition) that CISA confirmed as actively exploited on 2025-07-22 and that is tied to ransomware campaigns. With an EPSS score of 100 percent and a High severity rating of CVSS 8.8, this is part of the ToolShell wave hitting internet-facing SharePoint farms, so any organization running these servers should treat it as already targeted.
