Description
CVE-2026-116576 is an OS command injection vulnerability in the systeminformation Node.js library prior to version 5.33.16. The issue arises from improper sanitization of service names used in PowerShell commands on Windows, allowing an attacker to inject arbitrary PowerShell expressions. Exploitation requires local or forwarded attacker-controlled input to the vulnerable services() or getDynamicData() functions. The vulnerability is fixed in version 5.33.16.
