Senserva AI Opinion for CVE-2025-54100

PowerShell is the affected component in this High Severity (CVSS 8.8) remote code execution flaw on Windows 10 1809 and Windows Server 2019, which is notable because PowerShell is present and enabled on every one of those systems and heavily used by administrators. EPSS puts exploitation probability at 5 percent with no confirmed attacks or ransomware use.

Do this: Patch administrative jump boxes and management servers running Server 2019 first, since that is where PowerShell runs with the highest privileges.
