{"id":"CVE-2026-26280","state":"PUBLISHED","title":"Systeminformation has a Command Injection via unsanitized interface parameter in wifi.js retry path","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.","publishedAt":"2026-02-19T19:43:05.868Z","updatedAt":"2026-07-15T01:15:04.841Z","severity":{"score":8.4,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","source":"GitHub_M"},"assigner":"GitHub_M","products":["sebhildebrandt systeminformation"],"affected":[{"vendor":"sebhildebrandt","product":"systeminformation","versions":[{"version":"< 5.30.8","status":"affected"}]}],"references":["https://github.com/sebhildebrandt/systeminformation/security/advisories/GHSA-9c88-49p5-5ggf","https://github.com/sebhildebrandt/systeminformation/commit/22242aa56188f2bffcbd7d265a11e1ebb808b460","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"],"weaknesses":["CWE-78"],"ingestedAt":"2026-10-29T20:11:21.040Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/26xxx/CVE-2026-26280.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-26280","state":"PUBLISHED","datePublished":"2026-02-19T19:43:05.868Z","dateUpdated":"2026-07-15T01:15:04.841Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-02-12T17:10:53.414Z"},"containers":{"cna":{"title":"Systeminformation has a Command Injection via unsanitized interface parameter in wifi.js retry path","descriptions":[{"lang":"en","value":"systeminformation is a System and OS information library for node.js.
