Which packages are affected by CVE-2019-1003042?

CVE-2019-1003042 affects the following packages: org.6wind.jenkins:lockable-resources (Maven). Ecosystems affected: Maven.

How do I fix CVE-2019-1003042?

Update org.6wind.jenkins:lockable-resources to 2.5 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2019-1003042 is resolved across your whole dependency graph.

How do I detect CVE-2019-1003042 in my Maven dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.6wind.jenkins:lockable-resources, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate CVE-2019-1003042 if there is no patch (or I can't update yet)?

Escape or sanitise the affected output on the server side rather than relying on client-side filtering, and add a Content-Security-Policy that blocks inline script execution so injected markup cannot run even if it reaches the page.

Is CVE-2019-1003042 actively exploited in the wild?

No public exploit code has been indexed for CVE-2019-1003042 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.
