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
Jenkins Template Workflows Plugin 41.v32d86a_313b_4a and earlier does not escape names of jobs used as buildings blocks for Template Workflow Job, resulting in a stored cross-site scripting (XSS) vulnerability exploitable by attackers able to create jobs.

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

The Jenkins Template Workflows Plugin versions 41.v32d86a_313b_4a and earlier fails to properly escape job names used as building blocks when creating Template Workflow Jobs. This allows attackers with job creation privileges to inject malicious JavaScript code into job names, which executes in the browsers of other users who view the template job configuration or related pages.

MitigationUpdate the Jenkins Template Workflows Plugin to version 41.v32d86a_313b_4a or later. Until patched, restrict job creation permissions to trusted users only.

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 if Template Workflows Plugin is installed
    Go to Jenkins > Manage Jenkins > Manage Plugins > Installed tab and search for 'Template Workflows' or check the plugin directory $JENKINS_HOME/plugins for the template-workflows plugin folder
    Affected if The plugin is present in the plugins directory or listed in Installed plugins
  2. Determine the installed plugin version
    In Manage Jenkins > Manage Plugins > Installed tab, find Template Workflows and note the version number displayed in the version column
    Affected if Version is 41.v32d86a_313b_4a or earlier (the version string contains 41.v32d86a_313b_4a or a lower version number)
  3. Check for job creation permissions
    Go to Manage Jenkins > Manage Users and review who has the Overall/Administer or Job/Create permissions, or inspect $JENKINS_HOME/users/ directory for user directories
    Affected if Multiple users exist with job creation privileges, especially untrusted or anonymous users have this access
  4. Inspect existing Template Workflow Jobs for suspicious job names
    Browse to the Template Workflow jobs in Jenkins and examine job names. Look for jobs containing characters like <script>, javascript:, onerror=, or unusual encoded characters in the job name field
    Affected if Any Template Workflow Job exists with a job name containing XSS payloads such as <script> tags, javascript: URIs, or event handler attributes like onload/onerror

You are affected if the Template Workflows Plugin version is 41.v32d86a_313b_4a or earlier AND users with job creation permissions exist AND any Template Workflow Job has a suspicious name containing script tags or JavaScript event handlers.
