RCE in Sebhildebrandt Systeminformation

CVE-2026-44724

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.
