  "description": "### Summary\nA 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.\n\n### Details\nIn `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')`.\n\n### PoC\n1. Install `systeminformation@5.30.7`\n2. Call `si.wifiNetworks('eth0; id')`\n3. The first call sanitizes input, but if results are empty, the retry executes: `iwlist eth0; id scan`\n\n### Impact\nRemote Code Execution (RCE). Any application passing user-controlled input to `si.wifiNetworks()` is vulnerable to arbitrary command execution with the privileges of the Node.js process.",
