Description¶

systeminformation Command Injection vulnerability (CVSS 7.5). A severe command-injection vulnerability in systeminformation, a widely used Node.js library. The flaw allows attackers to execute arbitrary commands on Windows systems when applications pass user input to the vulnerable function. The vulnerability exists in the fsSize() function, which retrieves disk space information but fails to properly validate the optional drive parameter before passing it to PowerShell commands. An attacker can inject malicious PowerShell commands through the drive parameter. Patched in version 5.27.14 released on December 16, 2025.
