GHSA-7jh9-6cpf-h4m7
CRITICALGHSA-7jh9-6cpf-h4m7 is a critical-severity (CVSS 9.9) Cross-site Scripting (XSS) vulnerability in hellojs. O3 Security confirms whether GHSA-7jh9-6cpf-h4m7 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

hellojsnpmDescription
This affects the package hello.js before 1.18.6. The code get the param oauth_redirect from url and pass it to location.assign without any check and sanitisation. So we can simply pass some XSS payloads into the url param oauth_redirect, such as javascript:alert(1).

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for hellojs. 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.
Fix
Update hellojs to 1.18.6 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-7jh9-6cpf-h4m7 is resolved across your whole dependency graph.
Workarounds
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-7jh9-6cpf-h4m7 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-7jh9-6cpf-h4m7. 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-7jh9-6cpf-h4m7 in your dependencies?
O3 detects GHSA-7jh9-6cpf-h4m7 across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
