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."}],"affected":[{"source":"security-advisories@github.com","affectedData":[{"vendor":"sebhildebrandt","product":"systeminformation","versions":[{"version":"< 5.33.14","status":"affected"}]}]}],"metrics":{"cvssMetricV31":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N","baseScore":3.3,"baseSeverity":"LOW","attackVector":"LOCAL","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"LOW","integrityImpact":"NONE","availabilityImpact":"NONE"},"exploitabilityScore":1.8,"impactScore":1.4}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2026-10-28T14:34:17.124091Z","id":"CVE-2026-116673","options":[{"exploitation":"none"},{"automatable":"no"},{"technicalImpact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"weaknesses":[{"source":"security-advisories@github.com","type":"Secondary","description":[{"lang":"en","value":"CWE-22"},{"lang":"en","value":"CWE-59"}]}],"references":[{"url":"https://github.com/sebhildebrandt/systeminformation/commit/8d294b3139fec654a912969ac898037578a218cd","source":"security-advisories@github.com"},{"url":"https://github.com/sebhildebrandt/systeminformation/releases/tag/v5.33.14","source":"security-advisories@github.com"},{"url":"https://github.com/sebhildebrandt/systeminformation/security/advisories/GHSA-4vjg-vx72-qq4g","source":"security-advisories@github.com"}]}
