Senserva AI Opinion for CVE-2026-41095

Data Deduplication is a file server feature, and this Critical (CVSS 9.8) escalation in it affects the Server Core installations of Windows Server 2025, Server 2019, and Server 2022 23H2 Edition. The 72 percent EPSS exploit probability is high for a role-specific component, and dedup-enabled file servers concentrate exactly the data attackers want to reach after escalating. The Server Core focus means affected hosts are often headless and lightly monitored.

Do this: Enumerate servers with the Data Deduplication role enabled and patch those first, regardless of which Server version they run.
