GHSA-frqg-7g38-6gcf is a high-severity (CVSS 8.2) CWE-77 vulnerability in composer/composer. O3 Security confirms whether GHSA-frqg-7g38-6gcf is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Improper escaping of command arguments on Windows leading to command injection
Real-World Exposure
composer/composer🐘composer/composerReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Packagist packages — download data is not available via public APIs for these ecosystems.
Description
Impact
Windows users running Composer to install untrusted dependencies are affected and should definitely upgrade for safety. Other OSs and WSL are not affected.
Patches
1.10.23 and 2.1.9 fix the issue
Workarounds
None
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| 🐘Packagist | composer/composer | all versions | 1.10.23 |
| 🐘Packagist | composer/composer | ≥ 2.0.0-alpha1&&< 2.1.9 | 2.1.9 |
Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for composer/composer. 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 composer/composer to 1.10.23 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-frqg-7g38-6gcf 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-frqg-7g38-6gcf 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-frqg-7g38-6gcf. 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-frqg-7g38-6gcf in your dependencies?
O3 detects GHSA-frqg-7g38-6gcf across Packagist dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
