{"cve":"CVE-2026-26280","nvd":{"published":"2026-02-19T20:25:43.880","modified":"2026-07-15T02:19:01.387","status":"Modified","description":"systeminformation is a System and OS information library for node.js. In versions prior to 5.30.8, a command injection vulnerability in the `wifiNetworks()` function allows an attacker to execute arbitrary OS commands via an unsanitized network interface parameter in the retry code path. In `lib/wifi.js`, the `wifiNetworks()` function sanitizes the `iface` parameter on the initial call (line 437). However, when the initial scan returns empty results, a `setTimeout` retry (lines 440-441) calls `getWifiNetworkListIw(iface)` with the **original unsanitized** `iface` value, which is passed directly to `execSync('iwlist ${iface} scan')`. Any application passing user-controlled input to `si.wifiNetworks()` is vulnerable to arbitrary command execution with the privileges of the Node.js process. Version 5.30.8 fixes the issue.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.8},"cwes":["CWE-78"],"references":["https://github.com/sebhildebrandt/systeminformation/commit/22242aa56188f2bffcbd7d265a11e1ebb808b460","https://github.com/sebhildebrandt/systeminformation/security/advisories/GHSA-9c88-49p5-5ggf","https://access.redhat.com/security/cve/CVE-2026-26280","https://bugzilla.redhat.com/show_bug.cgi?id=2441121","https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-26280.json"],"products":["systeminformation:systeminformation"],"source":"nvd","synced_at":"2026-10-19T22:23:35.260773158+00:00"},"epss":{"cve":"CVE-2026-26280","score":0.01371,"percentile":0.71951,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-9c88-49p5-5ggf","url":"https://osv.dev/vulnerability/GHSA-9c88-49p5-5ggf","summary":"Systeminformation has a Command Injection via unsanitized interface parameter in wifi.js retry path","modified":"2026-09-10T03:50:34.457556318Z","packages":[{"ecosystem":"npm","name":"systeminformation","purl":"pkg:npm/systeminformation","ranges":["<5.30.8"],"fixed":["5.30.8"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
