GHSA-f8jj-45fj-44r6
CRITICALGHSA-f8jj-45fj-44r6 is a critical-severity (CVSS 9.8) vulnerability in js-she3. O3 Security confirms whether GHSA-f8jj-45fj-44r6 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Malicious Package in js-she3
Real-World Exposure
js-she3Real-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
Version 0.8.0 contained malicious code. The package targeted the Ethereum cryptocurrency and performed transactions to wallets not controlled by the user.
Recommendation
Remove the package from your environment. Ensure no Ethereum funds were compromised.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for js-she3. 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 js-she3 has shipped for GHSA-f8jj-45fj-44r6 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-f8jj-45fj-44r6 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-f8jj-45fj-44r6. 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-f8jj-45fj-44r6 in your dependencies?
O3 detects GHSA-f8jj-45fj-44r6 across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
