SCA: security update for systeminformation (GHSA-9c88-49p5-5ggf)

high Tenable Self-Hosted Container Security Plugin ID 437856

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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. (CVE-2026-26280)
