Doc Text:
A flaw was found in systeminformation. The library fails to properly validate user-supplied network interface names when querying network statistics on Linux systems. A local attacker who can control this parameter and create symbolic links on the local filesystem can exploit this path traversal flaw to retrieve file contents accessible to the application process, leading to information disclosure.

Description OSIDB Bzimport 2026-10-27 18:26:13 UTC 
systeminformation is a System and OS information library for node.js. Prior to 5.33.14, the Linux networkStats(iface) implementation uses the caller-supplied interface value in an fs.existsSync() check and to build /sys/class/net/<iface> paths, including the operstate path, without verifying that it is a single interface-name segment or that the resolved path remains under /sys/class/net. An attacker who can control iface and create a directory containing symlinked statistics files can use parent-directory components and symlink traversal to make the API return the first line of a file readable by the Node.js process. The package does not expose a network endpoint, and the demonstrated scenario requires local filesystem setup. This issue is fixed in version 5.33.14.
