{"id":"CVE-2026-26280","aliases":["GHSA-9c88-49p5-5ggf"],"url":"https://o3.security/vulnerability/CVE-2026-26280","summary":"Systeminformation has a Command Injection via unsanitized interface parameter in wifi.js retry path","details":"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.","published":"2026-02-19T19:43:05.868Z","modified":"2026-08-12T03:51:41.578403058Z","cvss":{"score":8.4,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"epss":{"score":0.01233,"percentile":0.67376,"asOf":"2026-09-15"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"systeminformation","fixedVersion":"5.30.8"}],"fix":{"url":"https://github.com/sebhildebrandt/systeminformation/commit/22242aa56188f2bffcbd7d265a11e1ebb808b460","label":"sebhildebrandt/systeminformation@22242aa"},"references":[{"type":"WEB","url":"https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-26280.json"},{"type":"ADVISORY","url":"https://access.redhat.com/security/cve/CVE-2026-26280"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/26xxx/CVE-2026-26280.json"},{"type":"ADVISORY","url":"https://github.com/sebhildebrandt/systeminformation/security/advisories/GHSA-9c88-49p5-5ggf"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-26280"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2441121"},{"type":"FIX","url":"https://github.com/sebhildebrandt/systeminformation/commit/22242aa56188f2bffcbd7d265a11e1ebb808b460"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:41.578403058Z"}}
