GHSA-h2p3-h48h-9jj7
CRITICALGHSA-h2p3-h48h-9jj7 is a critical-severity (CVSS 9.8) OS Command Injection vulnerability in pidusage. 1 public exploit reference exists, so weaponization risk is real. O3 Security confirms whether GHSA-h2p3-h48h-9jj7 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

pidusagenpmDescription
Overview
Affected versions of pidusage pass unsanitized input to child_process.exec(), resulting in arbitrary code execution in the ps method.
This package is vulnerable to this PoC on Darwin, SunOS, FreeBSD, and AIX.
Windows and Linux are not vulnerable.
Proof of Concept
var pid = require('pidusage');
pid.stat('1 && /usr/local/bin/python');
Remediation
Update to version 1.1.5 or later.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| 📦npm | pidusage | all versions | 1.1.5 |

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for pidusage. 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.
Fix
Update pidusage to 1.1.5 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-h2p3-h48h-9jj7 is resolved across your whole dependency graph.
Workarounds
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 O3 protects you
O3 pinpoints whether GHSA-h2p3-h48h-9jj7 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to GHSA-h2p3-h48h-9jj7. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-h2p3-h48h-9jj7 in your dependencies?
O3 detects GHSA-h2p3-h48h-9jj7 across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
