GHSA-9q9m-m2f6-jr5q
CRITICALGHSA-9q9m-m2f6-jr5q is a critical-severity (CVSS 9.8) vulnerability in chak. O3 Security confirms whether GHSA-9q9m-m2f6-jr5q is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Malicious Package in chak
Real-World Exposure
How broadly this vulnerability is actually deployed: weekly install volume shows current usage, a proxy for how much of the ecosystem is exposed.
chaknpmDescription
All versions of chak typosquatted a popular package of similar name and tracked users who had installed the incorrect package. The package uploaded information to a remote server including: name of the downloaded package, name of the intended package, the Node version and whether the process was running as sudo. There is no further compromise.
Recommendation
Remove the package from your dependencies and always ensure package names are typed correctly upon installation.
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 chak. 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 chak has shipped for GHSA-9q9m-m2f6-jr5q 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-9q9m-m2f6-jr5q 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-9q9m-m2f6-jr5q. 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-9q9m-m2f6-jr5q in your dependencies?
O3 detects GHSA-9q9m-m2f6-jr5q across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
