GHSA-8r4g-cg4m-x23c
Fix: cloudhead/node-static#213GHSA-8r4g-cg4m-x23c is a security vulnerability in node-static. O3 Security confirms whether GHSA-8r4g-cg4m-x23c is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Denial of Service in node-static
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.
node-staticnpmDescription
All versions of node-static are vulnerable to a Denial of Service. The package fails to catch an exception when user input includes null bytes. This allows attackers to access http://host/%00 and crash the server.
Affected Packages

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for node-static. 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 node-static has shipped for GHSA-8r4g-cg4m-x23c 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-8r4g-cg4m-x23c 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-8r4g-cg4m-x23c. 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-8r4g-cg4m-x23c in your dependencies?
O3 detects GHSA-8r4g-cg4m-x23c across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
