A caller who can create a symlink fixture and control the value passed to this API can make the function return the first line of a file readable by the Node process.\n\n### Details\n\nThe strict string sanitizer removes shell metacharacters but retains `/` and `.`. The Linux implementation uses this value in an `fs.existsSync('/sys/class/net/' + iface)` check and then in seven `cat` paths for interface statistics. Both operations follow `..` path components and symlinks. The code does not validate the value as an interface name or enforce resolved-path containment.\n\nThe proof of concept below creates the expected statistics files in a directory writable by the unprivileged `nobody` user. Its `operstate` symlink points to a synthetic mode-0600 file under `/root`. The package call runs as root and returns the marker even though `nobody` cannot read that file.\n\n### PoC\n\nUse a disposable Ubuntu Linux VM with Node.js, npm, and `runuser` installed.
