How severe is GHSA-9c88-49p5-5ggf?

GHSA-9c88-49p5-5ggf has a CVSS score of 8.4/10, rated HIGH. Immediate patching is strongly recommended.

Which packages are affected by GHSA-9c88-49p5-5ggf?

GHSA-9c88-49p5-5ggf affects the following packages: systeminformation (npm). Ecosystems affected: npm.

How do I fix GHSA-9c88-49p5-5ggf?

Update systeminformation to 5.30.8 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-9c88-49p5-5ggf is resolved across your whole dependency graph.

How do I detect GHSA-9c88-49p5-5ggf in my npm dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for systeminformation. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.

How do I mitigate GHSA-9c88-49p5-5ggf if there is no patch (or I can't update yet)?

If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

How does O3 Security protect against GHSA-9c88-49p5-5ggf?

O3 pinpoints whether GHSA-9c88-49p5-5ggf is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Is GHSA-9c88-49p5-5ggf actively exploited in the wild?

No public exploit code has been indexed for GHSA-9c88-49p5-5ggf yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for GHSA-9c88-49p5-5ggf?

GHSA-9c88-49p5-5ggf has an EPSS (Exploit Prediction Scoring System) score of 1.1%, placing it in the 62th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

When was GHSA-9c88-49p5-5ggf published, and has it been updated?

GHSA-9c88-49p5-5ggf was published on February 18, 2026 and was last updated on February 19, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Description

Summary

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.

Details

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').

PoC

Install [email protected]
Call si.wifiNetworks('eth0; id')
The first call sanitizes input, but if results are empty, the retry executes: iwlist eth0; id scan

Impact

Remote 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.
