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 Extended Choice Parameter Plugin is installed
    Navigate to Manage Jenkins > Manage Plugins > Installed tab and search for 'Extended Choice Parameter' in the list of installed plugins.
    Affected if The plugin is not installed or has been removed.
  2. Determine installed plugin version
    In the Installed plugins list, locate the Extended Choice Parameter plugin and note the Version column value (e.g., 346.vd87693c5a_86c).
    Affected if The version number is 346.vd87693c5a_86c or lower.
  3. Check if Item/Configure permission is exposed to untrusted users
    Navigate to Manage Jenkins > Manage Users and review which users exist. Then go to Manage Jenkins > Global Security and check if authorization allows untrusted or anonymous users to have Item/Configure or Item/Build permissions. Alternatively, check individual job-level permissions if per-item access control is enabled.
    Affected if Untrusted or anonymous users have Item/Configure permission.
  4. Identify exposed configuration using Extended Choice Parameter
    Navigate to Manage Jenkins > Global Tool Configuration or any job configuration pages. Review whether any parameter definitions use the Extended Choice Parameter plugin type (look for 'Extended Choice' in parameter types).
    Affected if Extended Choice parameters are configured and the plugin version is vulnerable.

Your environment is affected if the Extended Choice Parameter plugin version is 346.vd87693c5a_86c or lower AND untrusted users have Item/Configure permission, especially if Extended Choice parameters are actively used in job configurations.
