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 missing permission check in Jenkins FTP publisher Plugin in the FTPPublisher.DescriptorImpl#doLoginCheck method allows attackers with Overall/Read permission to initiate a connection to an attacker-specified server.

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 FTP publisher plugin for Jenkins has a missing permission check in the FTPPublisher.DescriptorImpl#doLoginCheck method. Any user with Overall/Read permission (the lowest privilege level in Jenkins) can trigger the Jenkins server to connect to an attacker-specified FTP server, enabling network-based attacks or server reconnaissance.

MitigationUpgrade the Jenkins FTP publisher plugin to the patched version. Additionally, restrict user permissions to the minimum required and consider network segmentation to limit the impact of server-initiated connections.

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 if FTP Publisher plugin is installed
    Navigate to Jenkins > Manage Jenkins > Manage Plugins > Installed tab, or use the Jenkins CLI: java -jar jenkins-cli.jar -s http://[jenkins-url] list-plugins | grep -i ftp
    Affected if The FTP Publisher plugin appears in the installed plugins list
  2. Confirm the plugin is enabled and loaded
    Check Jenkins > Manage Jenkins > System Information for 'FTP Publisher Plugin' presence, or inspect the Jenkins logs for plugin initialization messages containing 'FTP Publisher'
    Affected if The plugin is present and loaded in the Jenkins runtime
  3. Verify low-privilege user access exists
    Navigate to Jenkins > Manage Jenkins > Manage Users and check if any users exist with Overall/Read permission (default for authenticated users), or review Authorization Matrix settings
    Affected if Any user account exists that has Overall/Read permission (the default authenticated user level)

If the FTP Publisher plugin is installed and any user with Overall/Read permission exists in Jenkins, the environment is affected by this vulnerability.
