CVE-2026-26280
No affected components available
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.
The vulnerability requires local access to the device to be exploited. It is easy for an attacker to exploit this vulnerability. An attacker does not need any special privileges or access rights. No user interaction is needed for the attacker to exploit this vulnerability. The impact is confined to the system where the vulnerability exists. There is a high impact on the confidentiality of the information. There is a high impact on the integrity of the data. There is a high impact on the availability of the system.
Exploitation activity has been observed. Apply available patches or mitigations urgently.
The exploit probability is very low. The vulnerability is unlikely to be exploited in the next 30 days.
We did not find any exploit available. Neither in GitHub repositories nor in the Exploit-Database.
