Prior to 5.33.13, networkStats(ifaces) in lib/network.js on FreeBSD, OpenBSD, and NetBSD stores per-interface data in the plain-object _network cache and indexes it with the sanitized caller-controlled interface name. Passing proto causes the inherited Object.prototype value to be used instead of creating an own cache entry, so calcNetworkSpeed() writes rx_bytes, tx_bytes, rx_sec, tx_sec, ms, last_ms, and operstate onto Object.prototype. The polluted property names are fixed and their values come from interface statistics, but inherited-name collisions and enumerable keys can corrupt application branching, serialization, configuration merging, validation, or lookup behavior. This issue is fixed in version 5.33.13.","state":0,"publishedAt":"2026-10-27T17:16:59.453+00:00","modifiedAt":"2026-10-27T17:16:59.583+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:H/A:L","score":6.5,"severity":"MEDIUM"}],"references":["https://github.com/sebhildebrandt/systeminformation/commit/6ff25a1ebc0b1fdc7a8aa3507e46f22007da2969","https://github.com/sebhildebrandt/systeminformation/releases/tag/v5.33.13","https://github.com/sebhildebrandt/systeminformation/security/advisories/GHSA-7648-jmwf-vw7j"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-116674","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Deferred","weaknesses":["CWE-1321"],"productCriteria":[],"sourceDates":{"published":"2026-10-27T17:16:59.453","lastModified":"2026-10-27T17:16:59.583"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
