CVE-2025-68154Public exploitNetwork attack vector

Remote command execution via unsanitized drive parameter

Published Dec 16, 2025 · Updated Dec 16, 2025

OS command injection in systeminformation before 5.27.14 allows remote attackers to execute arbitrary commands on Windows via fsSize(). In lib/filesystem.js, fsSize() concatenates the optional drive parameter into a PowerShell pipeline without sanitizing shell metacharacters. Exploitation requires a consuming application to pass user-controlled input to fsSize(), and commands run with the Node.js process's privileges.
