CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:HSummary
CVE-2026-26280 is a high-severity OS Command Injection (CWE-78) vulnerability in Systeminformation Systeminformation. Its CVSS base score is 8.4 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Command and Scripting Interpreter (T1059); ranked in the top 34% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2026-26280 is a command injection vulnerability in the systeminformation library for Node.js, affecting versions prior to 5.30.8. The issue resides in the wifiNetworks() function within lib/wifi.js, where the network interface parameter (iface) is sanitized on the initial call (line 437). However, if the initial scan returns empty results, a setTimeout retry (lines 440-441) invokes getWifiNetworkListIw(iface) with the original unsanitized iface value, which is directly passed to execSync('iwlist ${iface} scan'). This allows arbitrary OS commands to be executed. The vulnerability is rated with a CVSS score of 8.4 (CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H) and is associated with CWE-78 (OS Command Injection).
A local attacker can exploit this vulnerability by providing malicious user-controlled input as the iface parameter to si.wifiNetworks() in any application using the library. No privileges are required (PR:N), and exploitation requires low complexity with local access (AV:L) but no user interaction (UI:N). Successful exploitation enables arbitrary command execution with the privileges of the Node.js process, potentially leading to high confidentiality, integrity, and availability impacts (C:H/I:H/A:H).
The GitHub security advisory (GHSA-9c88-49p5-5ggf) and the fixing commit (22242aa56188f2bffcbd7d265a11e1ebb808b460) confirm that upgrading to version 5.30.8 resolves the issue by ensuring proper sanitization in the retry path. Applications passing user-controlled input to si.wifiNetworks() should update immediately to mitigate the risk of command injection.

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.

Mitigating Controls (NIST 800-53 r5) AI
Developer testing and evaluation can discover missing or incorrect command sanitization during development.
Input validation directly neutralizes or rejects special characters that would otherwise alter OS command structure.
Least privilege reduces the permissions available to any process that could be subverted by injected commands.
Least functionality restricts available OS commands and interpreters, limiting the blast radius of injection.
Secure engineering principles require proper neutralization of untrusted input before command construction.

PR.PS-06's SDLC practices directly require secure coding and input handling that blocks command-injection defects, yet the single broad outcome leaves many specific neutralization vectors and verification gaps unaddressed.
Routine patching/maintenance can remediate known command-injection CVEs in dependencies (partial forward) but does nothing to stop developers from introducing improper neutralization in custom code (none reverse).
