Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
A sandbox bypass vulnerability involving casting an array-like value to an array type in Jenkins Script Security Plugin 1183.v774b_0b_0a_a_451 and earlier allows attackers with permission to define and run sandboxed scripts, including Pipelines, to bypass the sandbox protection and execute arbitrary code in the context of the Jenkins controller JVM.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify Script Security Plugin version
    Navigate to Manage Jenkins > Manage Plugins > Installed tab and locate Script Security Plugin, or inspect the plugin manifest file in JENKINS_HOME/plugins/script-security/WEB-INF/MANIFEST.MF
    Affected if Version is 1183.v774b_0b_0a_a_451 or earlier
  2. Confirm script execution permissions exist
    Review Jenkins authorization configuration (Manage Jenkins > Configure Global Security > Authorization) and check if any users or groups have Overall/Run Scripts or Job/Build permissions granted
    Affected if Any user or service account has script execution permissions enabled
  3. Check for Groovy sandbox usage
    Inspect pipeline jobs, Jenkinsfiles, or scripted build steps to determine if Groovy scripts are configured to run with sandbox enabled (script blocks using @Grab or sandbox() method)
    Affected if Pipeline or freestyle jobs use sandboxed Groovy script execution

If the Script Security Plugin version is 1183 or earlier and any user has script execution permissions in a sandboxed environment, the vulnerability is present.
