Which packages are affected by CVE-2019-10392?

CVE-2019-10392 affects the following packages: org.jenkins-ci.plugins:git-client (Maven). Ecosystems affected: Maven.

How do I fix CVE-2019-10392?

Update org.jenkins-ci.plugins:git-client to 2.8.5 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2019-10392 is resolved across your whole dependency graph.

How do I detect CVE-2019-10392 in my Maven dependencies?

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

How do I mitigate CVE-2019-10392 if there is no patch (or I can't update yet)?

Stop passing untrusted input into the interpreter or shell: call the affected binary with an argument array rather than a composed command string, reject anything outside a strict allowlist of expected values, and run the component under an account that cannot reach beyond the work it legitimately does.

Is CVE-2019-10392 actively exploited in the wild?

Yes. There are 6 known exploit references for CVE-2019-10392, including 3 in-the-wild exploitations observed on GitHub and other sources. Treat this as actively exploitable and prioritize patching immediately. All exploit code should only be run in an isolated sandbox environment for research or authorized testing — never against production systems without explicit written authorization.

What is the EPSS score for CVE-2019-10392?

CVE-2019-10392 has an EPSS (Exploit Prediction Scoring System) score of 23.1%, placing it in the 98th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score warrants monitoring and prompt remediation.
