GHSA-5mrr-rgp6-x4gr
GHSA-5mrr-rgp6-x4gr is a remote code execution vulnerability in marsdb. O3 Security confirms whether GHSA-5mrr-rgp6-x4gr is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Command Injection in marsdb
Real-World Exposure
marsdbReal-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 marsdb are vulnerable to Command Injection. In the DocumentMatcher class, selectors on $where clauses are passed to a Function constructor unsanitized. This allows attackers to run arbitrary commands in the system when the function is executed.
Recommendation
No fix is currently available. Consider using an alternative package until a fix is made available.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| 📦npm | marsdb | ≥ 0.0.0 | No fix |
Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for marsdb. 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 marsdb has shipped for GHSA-5mrr-rgp6-x4gr 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-5mrr-rgp6-x4gr 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-5mrr-rgp6-x4gr. 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-5mrr-rgp6-x4gr in your dependencies?
O3 detects GHSA-5mrr-rgp6-x4gr across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
