Which packages are affected by CVE-2014-1868?

CVE-2014-1868 affects the following packages: org.restlet.jse:org.restlet (Maven). Ecosystems affected: Maven.

How do I fix CVE-2014-1868?

Update org.restlet.jse:org.restlet to 2.1.7 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2014-1868 is resolved across your whole dependency graph.

How do I detect CVE-2014-1868 in my Maven dependencies?

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

How do I mitigate CVE-2014-1868 if there is no patch (or I can't update yet)?

Cap what an attacker can consume: apply request size, rate and timeout limits in front of the affected component, and run it with memory and CPU limits so exhaustion degrades one worker rather than the whole service.

Is CVE-2014-1868 actively exploited in the wild?

No public exploit code has been indexed for CVE-2014-1868 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.
