{"id":"UBUNTU-CVE-2026-116673","details":"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/\u003ciface\u003e 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.","modified":"2026-10-28T20:17:45.707826829Z","published":"2026-10-27T17:16:00Z","upstream":["CVE-2026-116673"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-116673"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-116673"},{"type":"REPORT","url":"https://github.com/sebhildebrandt/systeminformation/security/advisories/GHSA-4vjg-vx72-qq4g"},{"type":"REPORT","url":"https://github.com/sebhildebrandt/systeminformation/commit/8d294b3139fec654a912969ac898037578a218cd"},{"type":"REPORT","url":"https://github.com/sebhildebrandt/systeminformation/releases/tag/v5.33.14"}],"affected":[{"package":{"name":"node-systeminformation","ecosystem":"Ubuntu:26.10","purl":"pkg:deb/ubuntu/node-systeminformation?arch=source&distro=stonking"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["5.31.6-4","5.31.7-1"],"ecosystem_specific":{"binaries":[{"binary_name":"node-systeminformation","binary_version":"5.31.7-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-116673.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N"},{"type":"Ubuntu","score":"medium"}]}
