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 exists in Jenkins Groovy Plugin 2.1 and earlier in pom.xml, src/main/java/hudson/plugins/groovy/StringScriptSource.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 confidenceThe Jenkins Groovy Plugin 2.1 and earlier contains a sandbox bypass vulnerability in StringScriptSource.java that allows attackers with Overall/Read permission to execute arbitrary code on the Jenkins master JVM by circumventing Groovy sandbox restrictions.

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.
-
Identify if Jenkins Groovy Plugin is installedAccess Jenkins Manage Plugins page or use the Jenkins script console: Jenkins.instance.pluginManager.plugins.each { println "${it.shortName}: ${it.version}" }Affected if The plugin named 'groovy' appears in the list of installed plugins
-
Determine the installed version of Jenkins Groovy PluginLocate the groovy plugin entry in the plugin manager list and note the version number displayedAffected if The version is 2.1 or earlier (e.g., 2.1, 2.0, 1.x)
-
Verify Overall/Read permission assignmentNavigate to Manage Jenkins > Manage Users and check which users or groups have Overall > Read permission, or inspect configured authorization matrix settingsAffected if Any untrusted or unknown users are granted Overall/Read permission
-
Check if Groovy script execution features are accessibleLook for jobs, pipelines, or scripts that use Groovy-based script sources (StringScriptSource) which can be created by users with read accessAffected if Users with Overall/Read permission can create or modify Groovy script-based jobs or pipelines
You are affected if the Jenkins Groovy Plugin version is 2.1 or earlier AND untrusted users have Overall/Read permission, as this combination allows the sandbox bypass to be exploited.

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.
From vendor dataUpdate the Jenkins Groovy Plugin to version 2.2 or later to obtain the patched version. Until patched, strictly limit Overall/Read permission to trusted users only.
