CVE-2024-47764
Fix: jshttp/cookie@e100428CVE-2024-47764 is a CWE-74 vulnerability in cookie. O3 Security confirms whether CVE-2024-47764 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
cookie accepts cookie name, path, and domain with out of bounds characters
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.
cookienpmDescription
cookie is a basic HTTP cookie parser and serializer for HTTP servers. The cookie name could be used to set other fields of the cookie, resulting in an unexpected cookie value. A similar escape can be used for path and domain, which could be abused to alter other fields of the cookie. Upgrade to 0.7.0, which updates the validation for name, path, and domain.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| 📦npm | cookie | all versions | 0.7.0 |
Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for cookie. 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 cookie to 0.7.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2024-47764 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 CVE-2024-47764 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 CVE-2024-47764. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is CVE-2024-47764 in your dependencies?
O3 detects CVE-2024-47764 across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
