CVE-2026-50289 is a high-severity OS command injection vulnerability in the systeminformation library for node.js. Versions prior to 5.31.7 are affected. The vulnerability arises because the networkInterfaces() function on Linux reads and parses /etc/network/interfaces, extracting a source path token that is interpolated unquoted into a shell command executed via execSync. This allows an attacker to inject arbitrary shell commands if they can control the path value. The issue is fixed in version 5.31.7.

systeminformation is a System and OS information library for node.js. From 4.17.0 to 5.31.5, on Linux, systeminformation is vulnerable to command injection in networkInterfaces() when an active NetworkManager connection profile name contains shell metacharacters. The vulnerable value is obtained internally from real nmcli device status output. The library sanitizes the network interface name before using it in shell commands, but it does not apply equivalent sanitization to the parsed NetworkManager connection profile name. That unsanitized connectionName is then interpolated into three shell command strings executed through execSync(). This vulnerability is fixed in 5.31.6.

systeminformation is a System and OS information library for node.js. In versions prior to 5.27.14, the `fsSize()` function in systeminformation is vulnerable to OS command injection on Windows systems. The optional `drive` parameter is directly concatenated into a PowerShell command without sanitization, allowing arbitrary command execution when user-controlled input reaches this function. The actual exploitability depends on how applications use this function. If an application does not pass user-controlled input to `fsSize()`, it is not vulnerable. Version 5.27.14 contains a patch.
