GHSA-rc7h-x6cq-988q
CRITICALGHSA-rc7h-x6cq-988q is a critical-severity (CVSS 9.8) vulnerability in org.jgroups:jgroups. O3 Security confirms whether GHSA-rc7h-x6cq-988q is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Improper Input Validation in JGroups
Blast Radius
org.jgroups:jgroups☕org.jgroups:jgroupsReal-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
JGroups before 4.0 does not require the proper headers for the ENCRYPT and AUTH protocols from nodes joining the cluster, which allows remote attackers to bypass security restrictions and send and receive messages within the cluster via unspecified vectors. Fixes for this issue have been backported to versions 3.6.10.Final and 3.2.16.Final.
Affected Packages

|---|---|---|---|
| ☕Maven | org.jgroups:jgroups | ≥ 3.3.0.Alpha1&&< 3.6.10.Final | 3.6.10.Final |

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.jgroups:jgroups. 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.jgroups:jgroups to 3.6.10.Final or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-rc7h-x6cq-988q 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-rc7h-x6cq-988q 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-rc7h-x6cq-988q. 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-rc7h-x6cq-988q in your dependencies?
O3 detects GHSA-rc7h-x6cq-988q across Maven dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
