GHSA-vv52-3mrp-455m
GHSA-vv52-3mrp-455m is a security vulnerability in m-backdoor. O3 Security confirms whether GHSA-vv52-3mrp-455m is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Malicious Package in m-backdoor
Real-World Exposure
m-backdoorReal-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 m-backdoor contain malicious code. The package downloads a file from a remote server and executes it as a preinstall script. At the time of the release of this advisory the downloaded file only defaces websites by removing elements randomly from the DOM.
Recommendation
Remove the package from your system.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| 📦npm | m-backdoor | ≥ 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 m-backdoor. 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 m-backdoor has shipped for GHSA-vv52-3mrp-455m 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-vv52-3mrp-455m 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-vv52-3mrp-455m. 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-vv52-3mrp-455m in your dependencies?
O3 detects GHSA-vv52-3mrp-455m across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
