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
Missing permission checks in Jenkins Nexus Platform Plugin 3.18.0-03 and earlier allow attackers with Overall/Read permission to send an HTTP request to an attacker-specified URL and parse the response as XML.

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 Nexus Platform Plugin versions 3.18.0-03 and earlier lack proper permission checks on an endpoint, allowing any authenticated user with only Overall/Read permission to send HTTP requests to attacker-specified URLs and parse the resulting XML response. This is a Server-Side Request Forgery (SSRF) vulnerability combined with unsafe XML parsing, enabling potential internal network probing and XML-based attacks.

MitigationUpdate the Nexus Platform Plugin to a version later than 3.18.0-03, which includes proper permission validation. If immediate patching is not feasible, restrict Overall/Read permissions and limit network connectivity from the Jenkins controller.

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 Nexus Platform Plugin is installed
    Go to Manage Jenkins > Manage Plugins > Installed tab and search for 'Nexus Platform', or check the $JENKINS_HOME/plugins directory for a nexus-platform folder
    Affected if The plugin is present in Jenkins
  2. Check the installed version of Nexus Platform Plugin
    View the plugin details in the Installed Plugins UI, or inspect the manifest file at $JENKINS_HOME/plugins/nexus-platform/META-INF/MANIFEST.MF
    Affected if Version is 3.18.0-03 or earlier (the version number matches or is lower than the affected range)
  3. Confirm users with Overall/Read permission exist
    Navigate to Manage Jenkins > Configure Global Security and review the authorization matrix, or check if the security realm allows any authenticated user to have Overall/Read permission
    Affected if There are users or groups with only Overall/Read permission (this permission is often granted by default to authenticated users in standard security configurations)

Your environment is affected if the Nexus Platform Plugin version is 3.18.0-03 or earlier AND your Jenkins instance permits any authenticated user to have Overall/Read permission, as this combination allows the SSRF and unsafe XML parsing vulnerability to be exploited.

dbcve · scoped
Upgrade available Upgrade to a release after 3.18.0-03
Interim mitigation

Update the Nexus Platform Plugin to a version later than 3.18.0-03, which includes proper permission validation. If immediate patching is not feasible, restrict Overall/Read permissions and limit network connectivity from the Jenkins controller.

Recommended fix High confidence

3.18.0-04 or later

  1. 1. In Jenkins, go to Manage Jenkins > Manage Plugins
  2. 2. Click on the 'Installed' tab
  3. 3. Find 'Nexus Platform Plugin' in the list
