CVE-2020-2235 has a CVSS score of 6.5/10, rated MEDIUM. Review your exposure and patch according to your risk tolerance.

Which packages are affected by CVE-2020-2235?

CVE-2020-2235 affects the following packages: org.jenkins-ci.plugins:pipeline-maven (Maven). Ecosystems affected: Maven.

How do I fix CVE-2020-2235?

Update org.jenkins-ci.plugins:pipeline-maven to 3.8.3 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2020-2235 is resolved across your whole dependency graph.

How do I detect CVE-2020-2235 in my Maven dependencies?

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

How do I mitigate CVE-2020-2235 if there is no patch (or I can't update yet)?

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.

Is CVE-2020-2235 actively exploited in the wild?

No public exploit code has been indexed for CVE-2020-2235 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.

What is the EPSS score for CVE-2020-2235?

CVE-2020-2235 has an EPSS (Exploit Prediction Scoring System) score of 0.9%, placing it in the 59th 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 indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

1 pkg affected

☕org.jenkins-ci.plugins:pipeline-maven

Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects Maven packages — download data is not available via public APIs for these ecosystems.

Description

Pipeline Maven Integration Plugin 3.8.2 and earlier does not perform a permission check in a method implementing form validation.

This allows users with Overall/Read access to Jenkins to connect to an attacker-specified JDBC URL using attacker-specified credentials IDs obtained through another method, potentially capturing credentials stored in Jenkins.

Additionally, this form validation method does not require POST requests, resulting in a cross-site request forgery (CSRF) vulnerability.

Pipeline Maven Integration Plugin 3.8.3 requires POST requests and Job/Configure permission for the affected form validation method.
