CVE-2024-34145
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 · uneditedA sandbox bypass vulnerability involving sandbox-defined classes that shadow specific non-sandbox-defined classes in Jenkins Script Security Plugin 1335.vf07d9ce377a_e 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 checksWork through these to decide whether this CVE applies to you.
-
Verify Script Security Plugin versionNavigate to Manage Jenkins > Manage Plugins > Installed tab and locate the Script Security Plugin in the list. Note the version number displayed in the Version column.Affected if The installed version is 1335.vf07d9ce377a_e or lower.
-
Confirm Script Security sandbox is in useReview Jenkins jobs and Pipelines to identify any that use the sandboxed script execution feature, typically indicated by use of the Groovy sandbox in Pipeline scripts.Affected if Sandboxed script execution is enabled and in use within the Jenkins environment.
-
Identify users with script execution permissionsNavigate to Manage Jenkins > Manage Users and review permissions, or check if any users or groups have the Overall/Run Scripts or Script/Execute permission grants.Affected if Any user or group has permission to define and run sandboxed scripts.
The environment is affected if the Script Security Plugin version is 1335.vf07d9ce377a_e or lower and users with permission to run sandboxed scripts exist in the system.
Generated from the published advisory. Verify against your own configuration.
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 · scopedUpdate Jenkins Script Security Plugin to version 1336.vc_b_5f1a_3a_24 or later. Additionally, review and restrict permissions for who can define and run sandboxed scripts to minimize attack surface.
Script Security Plugin version 1336.vf20b_333f0a_2 or later
- Identify the current version of the Script Security plugin in Jenkins Manage Plugins
- If running version 1335.vf07d9ce377a_e or earlier, navigate to Manage Jenkins > Manage Plugins
- Locate Script Security plugin and select 'Update'
- Restart Jenkins controller to apply the update
- Verify the updated version is 1336.vf20b_333f0a_2 or later
