A sandbox bypass vulnerability exists in Script Security Plugin 1.47 and earlier in groovy-sandbox/src/main/java/org/kohsuke/groovy/sandbox/SandboxTransformer.java that allows attackers with Job/Configure permission to execute arbitrary code on the Jenkins master JVM, if plugins using the Groovy sandbox are installed.

Security readout for executives and security teams

Plain-English summary

This Jenkins issue lets a user who can configure jobs bypass Groovy sandbox protections and run arbitrary code on the Jenkins master JVM. That can turn a limited Jenkins permission into control of the build controller when Groovy-sandboxed plugins are present.

Executive priority

Treat as high priority for Jenkins controllers supporting production builds or deployments. The permission requirement lowers internet-scale risk, but compromise could affect software delivery integrity and secrets stored in Jenkins.

Technical view

CVE-2018-1000865 affects Jenkins Script Security Plugin 1.47 and earlier, specifically SandboxTransformer handling in groovy-sandbox. Attack requires Job/Configure permission and installed plugins using the Groovy sandbox. The documented impact is arbitrary code execution on the Jenkins master JVM.

Likely exposure

Exposure is most likely in Jenkins environments running Script Security Plugin 1.47 or earlier, with Groovy sandbox-using plugins installed, and non-administrators granted Job/Configure permission.

Exploitation context

The bundle does not show KEV listing or active exploitation evidence. Exploitation is permission-gated but high impact because successful abuse reaches the Jenkins master JVM.

Researcher notes

The available bundle identifies affected plugin versions and the permission and plugin preconditions, but does not include CVSS, CWE, exploit maturity, or detailed patch text. Validate fixes against Jenkins advisory SECURITY-1186 and any relevant Red Hat errata.

Mitigation direction

  • Review the Jenkins security advisory for the vendor-confirmed fixed version.
  • Update Script Security Plugin according to Jenkins and distribution vendor guidance.
  • Restrict Job/Configure permission to trusted administrators until remediated.
  • Review installed plugins that rely on the Groovy sandbox.

Validation and detection

  • Inventory Jenkins instances and Script Security Plugin versions.
  • Flag any instance running Script Security Plugin 1.47 or earlier.
  • Identify users and groups with Job/Configure permission.
  • Confirm whether Groovy sandbox-using plugins are installed.
  • Review recent job configuration changes for unexpected Groovy script edits.
