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 Shortcut Job Plugin 0.4 and earlier does not escape the shortcut redirection URL, resulting in a stored cross-site scripting (XSS) vulnerability exploitable by attackers able to configure shortcut 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 Shortcut Job Plugin versions 0.4 and earlier fails to escape/sanitize the shortcut redirection URL before rendering it in web pages, resulting in a stored cross-site scripting (XSS) vulnerability. Attackers with permission to configure shortcut jobs can inject malicious JavaScript code into the redirection URL that will execute in the browsers of users who view the affected pages.

MitigationUpgrade to Jenkins Shortcut Job Plugin version 0.5 or later which includes proper output encoding for the shortcut redirection URL. Until patched, restrict configuration permissions for shortcut jobs 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. Verify the Shortcut Job Plugin is installed
    Navigate to Jenkins > Manage Jenkins > Manage Plugins > Installed tab, then search for 'Shortcut Job' in the filter to confirm the plugin is present.
    Affected if The plugin does not appear in the installed plugins list, meaning it is not in use.
  2. Determine the installed version of the Shortcut Job Plugin
    In the Installed plugins tab, locate the Shortcut Job plugin and note the Version column displayed in the plugin table.
    Affected if The displayed version is 0.4 or lower (e.g., 0.4, 0.3, 0.2, 0.1, or any version number less than or equal to 0.4).
  3. Check if shortcut jobs exist in the system
    Use the Jenkins search or browse to jobs configured with the Shortcut Job type, or run: jenkins-cli.jar get-job [job-name] (if available) to inspect job configurations for shortcut job definitions.
    Affected if No jobs using the Shortcut Job plugin are configured in the Jenkins instance.
  4. Inspect job configurations for custom shortcut URLs
    For any existing shortcut jobs, navigate to the job configuration page and review the 'Shortcut URL' or redirection URL field to see if it contains user-supplied values.
    Affected if A shortcut job exists and the redirection URL field contains untrusted or externally supplied content.

You are affected if the Shortcut Job Plugin version is 0.4 or lower AND at least one shortcut job with a configured redirection URL exists in your Jenkins instance.

Upgrade available Upgrade to a release after 0.4
Interim mitigation

Upgrade to Jenkins Shortcut Job Plugin version 0.5 or later which includes proper output encoding for the shortcut redirection URL. Until patched, restrict configuration permissions for shortcut jobs to trusted users only.

Recommended fix Moderate confidence

Short Job Plugin version > 0.4 (check Jenkins Plugin Index for exact latest stable release)

  1. Navigate to Jenkins dashboard > Manage Jenkins > Manage Plugins
  2. Go to the 'Installed' tab
  3. Locate the 'Shortcut Job' plugin in the list
  4. Check the current version - if it is 0.4 or earlier, an upgrade is required
  5. Click on the plugin and select 'Update' or upgrade via the 'Available' tab if a newer version exists
  6. Restart Jenkins if required after the update
  7. Verify the fix by testing that the shortcut redirection URL is properly escaped and no XSS can be injected
