Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-116674/ (Markdown: https://insights.sbomify.com/CVE-2026-116674/index.md)","id":"CVE-2026-116674","markdown":"https://insights.sbomify.com/CVE-2026-116674/index.md","name":"CVE-2026-116674","record":{"aliases":["DEBIAN-CVE-2026-116674","ECHO-4aaa-1d80-7521","GHSA-7648-jmwf-vw7j","UBUNTU-CVE-2026-116674"],"analysis":null,"analysis_generated_by":null,"assigner":"GitHub_M","cpe":[],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:H/A:L","version":"3.1"},"cwes":[{"id":"CWE-1321","name":"Improperly Controlled Modification of Object Prototype Attributes"}],"description":"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.
