CVE-2026-26280 · Severity: high · CVSS 8.4 · Published 2026-02-19

systeminformation is a popular Node.js library used to retrieve system and hardware details. A security flaw in how it handles Wi-Fi network scanning allows an attacker to execute unauthorized commands on the underlying operating system. This could lead to a full system compromise, data theft, or service disruption, depending on the permissions of the application using the library.

Technologies: [systeminformation (npm)](https://junglewise.ai/threats/technologies/systeminformation), [Red Hat Developer Hub](https://junglewise.ai/threats/technologies/developer-hub). Vendors: [npm](https://junglewise.ai/threats/vendors/npm), [Red Hat](https://junglewise.ai/threats/vendors/red-hat).

## How to fix

- systeminformation (npm): upgrade to 5.30.8 or later

  ```sh
  npm install systeminformation@5.30.8
  ```


## Technical details

A command injection vulnerability (CWE-78) exists in the `wifiNetworks()` function within `lib/wifi.js`. While the library attempts to sanitize the `iface` parameter on the initial call, a `setTimeout` retry logic path fails to use the sanitized value if the initial scan returns empty results. This unsanitized input is passed directly to `execSync` via the `iwlist` command on Linux systems. An attacker who can control the interface name passed to this function can achieve arbitrary code execution with the privileges of the Node.js process. The issue is resolved in version 5.30.8.
