{"id":"UBUNTU-CVE-2026-26280","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.","modified":"2026-09-11T15:00:13.469289961Z","published":"2026-02-19T20:25:00Z","upstream":["CVE-2026-26280"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-26280"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-26280"}],"affected":[{"package":{"name":"jupyterlab","ecosystem":"Ubuntu:25.10","purl":"pkg:deb/ubuntu/jupyterlab?arch=source&distro=questing"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["4.0.11+ds1+~cs11.25.27-5","4.0.11+ds1+~cs11.25.27-6","4.0.11+ds1+~cs11.25.27-7"],"ecosystem_specific":{"binaries":[{"binary_name":"jupyterlab","binary_version":"4.0.11+ds1+~cs11.25.27-7"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-26280.json"}},{"package":{"name":"jupyterlab","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/jupyterlab?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["4.0.11+ds1+~cs11.25.27-7","4.0.11+ds1+~cs11.25.27-8","4.0.11+ds1+~cs11.25.27-9"],"ecosystem_specific":{"binaries":[{"binary_name":"jupyterlab","binary_version":"4.0.11+ds1+~cs11.25.27-9"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-26280.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},{"type":"Ubuntu","score":"medium"}]}
