{"schema":"threatline.record/2","record":{"id":"CVE-2026-116674","aliases":["GHSA-7648-jmwf-vw7j"],"summary":"systeminformation: Prototype pollution in `networkStats()` via the interface name","details":"systeminformation is a System and OS information library for node.js. 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.","categories":["Unclassified"],"product":"systeminformation","vendor":"sebhildebrandt","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-116674","source_modified_at":"2026-10-27T16:40:46.246Z","fetched_at":"2026-10-27T21:14:11.489891Z","product":"systeminformation","vendor":"sebhildebrandt","versions":[{"version":"< 5.33.13","status":"affected"}],"defaultStatus":null}],"fixed_versions":[],"cvss":6.5,"severity":"Medium","kev":{"listed":false},"epss":{"probability":null,"percentile":null,"score_date":null},"published_at":"2026-10-27T16:40:46.246Z","modified_at":"2026-10-27T16:40:46.246Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-116674","fetched_at":"2026-10-27T21:14:11.489891Z","source_modified_at":"2026-10-27T16:40:46.246Z"}],"sources":["CVE List"],"references":[{"source":"CVE List","url":"https://github.com/sebhildebrandt/systeminformation/security/advisories/GHSA-7648-jmwf-vw7j","tags":["x_refsource_CONFIRM"]},{"source":"CVE List","url":"https://github.com/sebhildebrandt/systeminformation/commit/6ff25a1ebc0b1fdc7a8aa3507e46f22007da2969","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/sebhildebrandt/systeminformation/releases/tag/v5.33.13","tags":["x_refsource_MISC"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-27T16:40:46.246Z","content_hash":"e1bef72a26938afa07d9ee3ab423e9eef720e89e2ebe4a448b8e49d9efcfa3af"}}
