Real-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

GraphQL Java (aka graphql-java) before 21.5 does not properly consider ExecutableNormalizedFields (ENFs) as part of preventing denial of service via introspection queries. 20.9 and 19.11 are also fixed versions.

Detection & mitigation playbook

Open-source dependency
  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for com.graphql-java:graphql-java. 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.

  2. Fix

    Update com.graphql-java:graphql-java to 19.11 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-h9mq-f6q5-6c8m is resolved across your whole dependency graph.

  3. 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.

  4. How O3 protects you

    O3 pinpoints whether GHSA-h9mq-f6q5-6c8m 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-h9mq-f6q5-6c8m. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.

O3 Security · Impact-Aware SCA

Is GHSA-h9mq-f6q5-6c8m in your dependencies?

O3 detects GHSA-h9mq-f6q5-6c8m across Maven dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
