GHSA-3393-hvrj-w7v3
MEDIUMGHSA-3393-hvrj-w7v3 is a medium-severity (CVSS 5.7) CWE-674 vulnerability in org.elasticsearch:elasticsearch. O3 Security confirms whether GHSA-3393-hvrj-w7v3 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Denial of Service in Elasticsearch
Real-World Exposure
org.elasticsearch:elasticsearch☕org.elasticsearch:elasticsearchReal-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
In Elasticsearch versions before 7.13.3 and 6.8.17 an uncontrolled recursion vulnerability that could lead to a denial of service attack was identified in the Elasticsearch Grok parser. A user with the ability to submit arbitrary queries to Elasticsearch could create a malicious Grok query that will crash the Elasticsearch node.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| ☕Maven | org.elasticsearch:elasticsearch | all versions | 6.8.17 |
| ☕Maven | org.elasticsearch:elasticsearch | ≥ 7.0.0-alpha1&&< 7.13.3 | 7.13.3 |
Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.elasticsearch:elasticsearch. 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 org.elasticsearch:elasticsearch to 6.8.17 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-3393-hvrj-w7v3 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-3393-hvrj-w7v3 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-3393-hvrj-w7v3. 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-3393-hvrj-w7v3 in your dependencies?
O3 detects GHSA-3393-hvrj-w7v3 across Maven dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
