GHSA-54qm-37qr-w5wq
GHSA-54qm-37qr-w5wq is a remote code execution vulnerability in veval. O3 Security confirms whether GHSA-54qm-37qr-w5wq is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Sandbox Breakout / Arbitrary Code Execution in veval
Real-World Exposure
vevalReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects npm packages — download data is not available via public APIs for these ecosystems.
Description
All versions of veval are vulnerable to Sandbox Escape leading to Remote Code Execution. The package fails to restrict access to the main context through this.constructor.constructor . This may allow attackers to execute arbitrary code in the system. Evaluating the payload this.constructor.constructor('return process.env')() prints the contents of process.env.
Recommendation
No fix is currently available. Consider using an alternative package until a fix is made available.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for veval. 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.
Remediation status
No patched version of veval has shipped for GHSA-54qm-37qr-w5wq yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
Mitigate without a patch
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-54qm-37qr-w5wq 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-54qm-37qr-w5wq. 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-54qm-37qr-w5wq in your dependencies?
O3 detects GHSA-54qm-37qr-w5wq across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
