CVE-2020-2256
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 · uneditedJenkins Pipeline Maven Integration Plugin 3.9.2 and earlier does not escape the upstream job's display name shown as part of a build cause, resulting in a stored cross-site scripting (XSS) vulnerability exploitable by attackers with Job/Configure permission.
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 · moderate confidenceThe Jenkins Pipeline Maven Integration Plugin versions 3.9.2 and earlier fail to properly escape the upstream job's display name when displaying it as part of a build cause. This allows stored XSS because malicious HTML/JavaScript embedded in the job display name is rendered unescaped in the web UI. Attackers with Job/Configure permission can inject scripts that execute when other users view build causes.

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 Pipeline Maven Integration Plugin is installedNavigate to Manage Jenkins > Manage Plugins > Installed tab and search for 'Pipeline Maven Integration', or use the Jenkins CLI: java -jar jenkins-cli.jar list-plugins | findstr mavenAffected if The plugin appears in the list of installed plugins
-
Determine the installed version of the pluginIn Manage Jenkins > Manage Plugins > Installed, find Pipeline Maven Maven Integration and note the Version column, or query the plugin via API: curl -s http://JENKINS_URL/pluginManager/plugin/pipeline-maven-integration/api/json?pretty=trueAffected if The displayed version is 3.9.2 or lower (e.g., 3.9.2, 3.9.1, 3.9.0, earlier)
-
Check if Maven pipeline jobs with upstream/downstream relationships existReview Jenkins jobs that use Maven pipelines and look for jobs configured with build triggers that create upstream/downstream relationships (e.g., 'Build after other projects are built' trigger)Affected if You have Maven pipeline jobs with upstream job references configured as build triggers
-
Identify if Job/Configure permission is broadly grantedReview Job-based authorization matrix or matrix authorization strategy in Manage Jenkins > Configure Global Security. Check which users or groups have the 'Job/Configure' permission at the job or folder levelAffected if Users or groups beyond trusted administrators have Job/Configure permission, allowing them to modify job configurations and display names
You are affected if the Pipeline Maven Integration Plugin is installed at version 3.9.2 or earlier and you have Maven pipeline jobs with upstream build triggers configured, particularly if users with Job/Configure permission are not restricted to trusted administrators.
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.
From vendor dataUpdate the Jenkins Pipeline Maven Integration Plugin to version 3.9.3 or later which includes proper HTML escaping of the upstream job display name. Until patched, restrict Job/Configure permission to trusted users only.
