GHSA-wh69-wc6q-7888 is a high-severity (CVSS 8.6) Code Injection vulnerability in dns-sync. O3 Security confirms whether GHSA-wh69-wc6q-7888 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

Real-World Exposure
How broadly this vulnerability is actually deployed: weekly install volume shows current usage, and reverse-dependency count shows how many other packages break if it stays unpatched.
dns-syncnpmDescription
dns-sync through 0.2.0 allows execution of arbitrary commands . This issue may lead to remote code execution if a client of the library calls the vulnerable method with untrusted input.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| 📦npm | dns-sync | ≥ 0.1.3&&< 0.2.1 | 0.2.1 |
Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for dns-sync. 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 dns-sync to 0.2.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-wh69-wc6q-7888 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-wh69-wc6q-7888 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-wh69-wc6q-7888. 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-wh69-wc6q-7888 in your dependencies?
O3 detects GHSA-wh69-wc6q-7888 across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
