GHSA-2w7w-2j92-44hx is a medium-severity (CVSS 6.5) CWE-444 vulnerability in com.typesafe.akka:akka-http-core. O3 Security confirms whether GHSA-2w7w-2j92-44hx is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

Real-World Exposure
com.typesafe.akka:akka-http-core☕com.typesafe.akka:akka-http-coreReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Maven packages — download data is not available via public APIs for these ecosystems.
Description
A vulnerable Akka HTTP server will accept a malformed message and hand it over to the user. If the user application proxies this message to another server unchanged and that server also accepts that message but interprets it as two HTTP messages, the second message has reached the second server without having been inspected by the proxy.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| ☕Maven | com.typesafe.akka:akka-http-core | ≥ 10.2.0&&< 10.2.4 | 10.2.4 |
| ☕Maven | com.typesafe.akka:akka-http-core | all versions | 10.1.14 |
Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for com.typesafe.akka:akka-http-core. 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 com.typesafe.akka:akka-http-core to 10.2.4 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-2w7w-2j92-44hx 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-2w7w-2j92-44hx 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-2w7w-2j92-44hx. 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-2w7w-2j92-44hx in your dependencies?
O3 detects GHSA-2w7w-2j92-44hx across Maven dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
