Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.hornetq.rest:hornetq-rest, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update org.hornetq.rest:hornetq-rest to 2.5.0.Beta1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2014-3599 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.
Fixing This On Your OS
If you run this on a Linux distribution, patch through your package manager against the distro's own security advisory below — it tracks the exact backported fix for your release, which can ship on a different timeline (and sometimes a different severity) than the upstream project.
Not Vulnerable. HornetQ REST is not provided by any Red Hat product.
When using HornetQ REST in an application, add the following snippet to its web.xml file to disable entity expansion in RESTEasy as used by HornetQ REST endpoints: <context-param> <param-name>resteasy.document.expand.entity.references</param-name> <param-value>false</param-value> </context-param> Note that this <context-param> setting has precedence over <init-param>, and will override a contrary setting in an <init-param> element.Source: Red Hat security advisory for CVE-2014-3599 (CC BY 4.0)
