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 Persona Plugin 2.4 and earlier allows users with Overall/Read permission to read arbitrary files on the Jenkins controller.

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 Persona Plugin versions 2.4 and earlier contains an arbitrary file read vulnerability. Users with the lowest privilege level (Overall/Read permission) can exploit this to read any file on the Jenkins controller file system, potentially exposing sensitive configuration, credentials, or secrets.

MitigationUpgrade the Jenkins Persona Plugin to version 2.5 or later, which contains the fix for this vulnerability. Restrict plugin installations and review user permissions until the patch can be applied.

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 Jenkins Persona Plugin is installed
    Navigate to Jenkins > Manage Jenkins > Manage Plugins > Installed tab, or use the Jenkins script console with: Jenkins.instance.pluginManager.plugins.find{it.shortName == 'persona'}
    Affected if The plugin is listed as installed in Jenkins
  2. Determine the installed version of Persona Plugin
    In the Installed plugins tab, locate 'Persona' and note the Version column, or query via script console: Jenkins.instance.pluginManager.plugins.find{it.shortName == 'persona'}.version
    Affected if The version number is 2.4 or lower (e.g., 2.4, 2.3, 2.2, etc.)
  3. Confirm user permissions configuration
    Review user permissions in Jenkins > Manage Jenkins > Manage Users, and check Overall permissions in Configure Global Security or Matrix-based security settings
    Affected if Any user or group is granted Overall/Read permission, which is the minimum required to exploit this vulnerability
  4. Identify if the vulnerable file read endpoint is accessible
    The vulnerability allows reading arbitrary files via plugin-specific URLs. If unauthenticated or low-privilege users can make HTTP requests to Jenkins, they can exploit this flaw
    Affected if Jenkins is accessible to users with only Overall/Read permission, or the plugin's API endpoints are reachable without higher privileges

Your environment is affected if the Jenkins Persona Plugin version 2.4 or earlier is installed AND any user has Overall/Read permission, allowing them to read arbitrary files on the Jenkins controller.
