OS Command Injection in systeminformation fsSize() on Windows
CVE-2025-68154 is an OS command injection vulnerability in the Node.js library systeminformation affecting versions prior to 5.27.14. On Windows systems, the vulnerable code path is in the fsSize() function, where the optional drive parameter is directly concatenated into a PowerShell command without proper sanitization or validation. If an application passes attacker-controlled input into fsSize(), an attacker can inject additional shell metacharacters or commands and cause arbitrary command execution. The issue is application-dependent: deployments are only exploitable when untrusted input can reach fsSize() on a Windows host.
