GHSA-m4fq-xh7w-jhfm
CRITICALGHSA-m4fq-xh7w-jhfm is a critical-severity (CVSS 9.1) vulnerability in crytpo-js. O3 Security confirms whether GHSA-m4fq-xh7w-jhfm is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Malicious Package in crytpo-js
Real-World Exposure
crytpo-jsReal-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 this package contained malware. The package was designed to find and exfiltrate cryptocurrency wallets.
Recommendation
Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer.
The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for crytpo-js. 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 crytpo-js has shipped for GHSA-m4fq-xh7w-jhfm 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-m4fq-xh7w-jhfm 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-m4fq-xh7w-jhfm. 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-m4fq-xh7w-jhfm in your dependencies?
O3 detects GHSA-m4fq-xh7w-jhfm across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
