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
A exposure of sensitive information vulnerability exists in Jenkins Configuration as Code Plugin 0.7-alpha and earlier in ConfigurationAsCode.java that allows attackers with Overall/Read access to obtain the YAML export of the Jenkins configuration.

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 Configuration as Code Plugin versions 0.7-alpha and earlier allows any user with Overall/Read access to export the full Jenkins configuration as YAML through ConfigurationAsCode.java. This exposes potentially sensitive configuration details including credentials, secrets, and system settings that should not be visible to standard read-only users.

MitigationUpgrade the Jenkins Configuration as Code Plugin to a version newer than 0.7-alpha that includes proper access control checks on the YAML export functionality, or implement role-based restrictions to limit which users can access configuration export features.

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 Configuration as Code plugin is installed
    Navigate to Manage Jenkins > Manage Plugins > Installed tab and search for 'Configuration as Code' plugin, or use the Jenkins CLI: java -jar jenkins-cli.jar -s http://[jenkins-url] list-plugins | grep -i configuration-as-code
    Affected if The plugin appears in the installed plugins list
  2. Determine the installed plugin version
    In the Installed Plugins tab, locate the 'Configuration as Code' plugin and note the Version column. Alternatively, check the plugin's manifest file in JENKINS_HOME/plugins/configuration-as-code/WEB-INF/lib/configuration-as-code.jar or the <plugin>.jpi file for version metadata.
    Affected if Version is 0.7-alpha or earlier, or any of these: 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7
  3. Confirm the export endpoint is accessible
    Attempt to access the YAML export URL at /configuration-as-code/export by logging in with a regular user account that has only Overall/Read permissions. For example: curl -u <readonly-user>:<password> http://[jenkins-url]/configuration-as-code/export
    Affected if The endpoint returns YAML configuration data without requiring elevated privileges beyond Overall/Read access
  4. Verify if any user with read access can export secrets
    With a standard read-only user account, attempt to retrieve the full configuration export and inspect whether it contains credential details, secrets, or sensitive system configuration that should not be visible to read-only users.
    Affected if The export contains credentials, secrets, passwords, tokens, or other sensitive configuration data that should be restricted from read-only users

Your environment is affected if the Configuration as Code plugin version is 0.7-alpha or earlier and any user with basic read access can export the full Jenkins configuration including sensitive credentials and secrets.

Mitigation

Upgrade the Jenkins Configuration as Code Plugin to a version newer than 0.7-alpha that includes proper access control checks on the YAML export functionality, or implement role-based restrictions to limit which users can access configuration export features.
