CVE-2026-116576 Details
Description
systeminformation is a System and OS information library for node.js. Prior to 5.33.16, services() in lib/processes.js inserts a caller-supplied service name into a PowerShell Get-CimInstance filter after processing it with sanitizeShellString() in lib/util.js. On Windows, the sanitizer removes ASCII quotes but permits Unicode quotation marks that PowerShell accepts as string delimiters, allowing crafted input to terminate the filter and place a PowerShell expression in the command executed by util.powerShell(). The expression runs with the Node.js process account's permissions and may read or change accessible files, alter application data, or disrupt the service. The package does not expose a network service itself, so remote reachability depends on a consuming application forwarding attacker-controlled input to services() or getDynamicData(). This issue is fixed in version 5.33.16.
A command injection vulnerability has been identified in the systeminformation library for Node.js, specifically in versions prior to 5.33.16. The issue arises in the services() function, where user-supplied service names are inserted into a PowerShell Get-CimInstance filter. The input is initially processed by a sanitizer that removes ASCII quotes but allows Unicode quotation marks, which PowerShell accepts as string delimiters. This oversight enables crafted input to escape the filter and execute arbitrary PowerShell commands with the permissions of the Node.js process account. While the package does not itself expose a network service, the vulnerability could be exploited remotely if an application forwards attacker-controlled input to the services() function or the getDynamicData() method.
Users can upgrade to systeminformation version 5.33.16 or later, where this vulnerability has been fixed.
