Which packages are affected by CVE-2018-1000601?

CVE-2018-1000601 affects the following packages: org.jenkins-ci.plugins:ssh-credentials (Maven), org.jenkins-ci.plugins:credentials (Maven). Ecosystems affected: Maven.

How do I fix CVE-2018-1000601?

Update org.jenkins-ci.plugins:ssh-credentials to 1.14 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2018-1000601 is resolved across your whole dependency graph.

How do I detect CVE-2018-1000601 in my Maven dependencies?

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

How do I mitigate CVE-2018-1000601 if there is no patch (or I can't update yet)?

Assume what was exposed is already known: rotate any credential, token or key that the affected component could return, restrict the endpoint to callers that genuinely need it, and strip sensitive fields from responses and error output at the boundary rather than relying on the client not to read them.

Is CVE-2018-1000601 actively exploited in the wild?

No public exploit code has been indexed for CVE-2018-1000601 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.
