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 cross-site request forgery vulnerability in Jenkins openid Plugin in the OpenIdSsoSecurityRealm.DescriptorImpl#doValidate form validation method allows attackers 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

CSRF vulnerability in Jenkins openid Plugin's OpenIdSsoSecurityRealm.DescriptorImpl#doValidate form validation method allows attackers to trick the Jenkins server into initiating connections to attacker-specified servers via forged requests.

MitigationUpdate to a patched version of the openid plugin, or remove/disable the plugin if not needed. Ensure global Jenkins CSRF protection is enabled as an additional defense layer.

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. Check if openid plugin is installed
    Navigate to Manage Jenkins > Manage Plugins > Installed tab, or run: Jenkins.instance.pluginManager.getPlugin('openid') in the script console
    Affected if The plugin appears in the installed plugins list
  2. Check if openid plugin is configured as security realm
    Run in Jenkins script console: Jenkins.instance.getSecurityRealm().getClass().getName() or inspect Configure Global Security page
    Affected if The security realm is set to 'OpenID SSO' or class contains 'OpenIdSsoSecurityRealm'
  3. Verify if the vulnerable form validation endpoint is accessible
    Check if the plugin's doValidate endpoint is reachable at /securityRealm/descriptorByName/org.jenkinsci.plugins.openid.OpenIdSsoSecurityRealm/doValidate
    Affected if The endpoint responds (plugin is active and processing requests)
  4. Check global CSRF protection status
    Navigate to Manage Jenkins > Configure Global Security and verify 'Crumb' or CSRF Protection is enabled
    Affected if CSRF protection is disabled (additional defense layer missing)

If the openid plugin is installed and configured as the security realm, and CSRF protection is disabled, the environment is vulnerable to CVE-2019-1003098
