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.","state":0,"publishedAt":"2026-10-27T16:38:15.558+00:00","modifiedAt":"2026-10-28T16:15:47.864+00:00","affected":[{"ecosystem":"Vendor product","name":"systeminformation","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"sebhildebrandt\",\n                    \"product\": \"systeminformation\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 5.33.14\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N","score":3.3,"severity":"LOW"}],"references":["https://github.com/sebhildebrandt/systeminformation/security/advisories/GHSA-4vjg-vx72-qq4g","https://github.com/sebhildebrandt/systeminformation/commit/8d294b3139fec654a912969ac898037578a218cd","https://github.com/sebhildebrandt/systeminformation/releases/tag/v5.33.14"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-116673","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-116673","identifiers":["CVE-2026-116673"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
