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 exists in Jenkins Script Security Plugin 1.53 and earlier in src/main/java/org/jenkinsci/plugins/scriptsecurity/sandbox/groovy/GroovySandbox.java, src/main/java/org/jenkinsci/plugins/scriptsecurity/sandbox/groovy/SecureGroovyScript.java that allows attackers with Overall/Read permission to execute arbitrary code on the Jenkins master 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.

dbcve analysis · high confidence

A sandbox bypass vulnerability in Jenkins Script Security Plugin 1.53 and earlier in GroovySandbox.java and SecureGroovyScript.java allows attackers with Overall/Read permission to execute arbitrary code on the Jenkins master JVM by circumventing script security restrictions.

MitigationUpgrade Jenkins Script Security Plugin to version 1.54 or later to resolve the sandbox bypass. Verify existing approved scripts continue functioning properly after the upgrade.

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. Verify Script Security Plugin is installed
    Navigate to Jenkins > Manage Jenkins > Manage Plugins > Installed tab and look for 'Script Security' in the list, or check the $JENKINS_HOME/plugins directory for the script-security folder
    Affected if The plugin is present in the plugin list or filesystem
  2. Determine the installed version of Script Security Plugin
    In Jenkins > Manage Jenkins > Manage Plugins > Installed tab, find Script Security and note the Version column; alternatively, check the version file in $JENKINS_HOME/plugins/script-security/META-INF/MANIFEST.MF
    Affected if The version number is 1.53 or earlier
  3. Confirm Groovy sandbox is in use
    Look for Pipeline jobs, Jenkinsfile executions, or Groovy scripts that use the sandboxed execution mode; check job configurations for 'Use Groovy Sandbox' checkbox enabled under the Pipeline Script section
    Affected if Groovy sandbox (GroovySandbox.java or SecureGroovyScript.java) is being used to execute scripts
  4. Check for Overall/Read permission assignments
    Navigate to Jenkins > Manage Jenkins > Manage Users and review user accounts, then check Jenkins > Manage Jenkins > Configure Global Security > Authorization to see which users or groups have Overall/Read permission
    Affected if Any user account or group has Overall/Read permission granted (especially untrusted or shared accounts)
  5. Verify if untrusted users can access Jenkins
    Review the authorization matrix in Jenkins > Manage Jenkins > Configure Global Security to identify which users or groups have Overall/Read access, particularly looking for users beyond trusted administrators
    Affected if Untrusted or unauthorized users have Overall/Read access to the Jenkins instance

You are affected if Jenkins Script Security Plugin version 1.53 or earlier is installed, Groovy sandbox execution is enabled, and untrusted users have Overall/Read permission to access Jenkins.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

dbcve · scoped
Upgrade available Upgrade to a release after 1.53
Interim mitigation

Upgrade Jenkins Script Security Plugin to version 1.54 or later to resolve the sandbox bypass. Verify existing approved scripts continue functioning properly after the upgrade.

Recommended fix High confidence

Script Security Plugin version 1.54 or later

  1. Log in to Jenkins as an administrator with overall admin permission
  2. Navigate to 'Manage Jenkins' > 'Manage Plugins'
  3. Click on the 'Installed' tab to view installed plugins
  4. Locate the 'Script Security' plugin in the list
  5. Verify the current installed version is 1.53 or earlier
  6. If an update is available, select the Script Security plugin and click 'Update'
  7. Alternatively, if no update is shown, download the fixed version from the Jenkins plugin repository manually
  8. Restart Jenkins after the plugin update to ensure the new version is loaded
Caveat Review pipeline scripts and Groovy code for compatibility after upgrade, as sandbox behavior may change
