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 exposure of sensitive information vulnerability exists in Jenkins GitHub Pull Request Builder Plugin 1.41.0 and older in GhprbGitHubAuth.java that allows attackers with Overall/Read access to connect to an attacker-specified URL using attacker-specified credentials IDs obtained through another method, capturing credentials stored in Jenkins.

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 GitHub Pull Request Builder Plugin versions 1.41.0 and older contains a flaw in GhprbGitHubAuth.java where attackers with Overall/Read access can specify arbitrary URLs and credentials IDs to connect to attacker-controlled endpoints, enabling capture of Jenkins-stored credentials.

MitigationUpgrade Jenkins GitHub Pull Request Builder Plugin to a version newer than 1.41.0, then review and rotate any credentials that may have been exposed.

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 plugin version
    Navigate to Manage Jenkins > Manage Plugins > Installed tab, locate 'GitHub Pull Request Builder' (ghprb) plugin, and check the Version column
    Affected if Version listed is 1.41.0 or lower (or if version cannot be determined but plugin is present and older)
  2. Confirm plugin is configured
    Navigate to Manage Jenkins > Configure System > find 'GitHub Pull Request Builder' section. Check if any GitHub API credentials or server URL are configured
    Affected if Plugin has any GitHub credentials or server URL configured and the plugin version is vulnerable
  3. Review credential usage
    Navigate to Manage Jenkins > Credentials > review any credentials with 'ghprb' or 'GitHub Pull Request Builder' in the description or tied to the plugin's scope
    Affected if Credentials exist that were used by the vulnerable plugin configuration
  4. Check for external endpoint configuration
    In the plugin configuration (Configure System > GitHub Pull Request Builder), examine the 'GitHub Server URL' and any override settings for repository webhooks
    Affected if Non-standard GitHub API URLs are configured pointing to external/ attacker-controlled endpoints

User is affected if Jenkins has GitHub Pull Request Builder plugin version 1.41.0 or lower installed AND the plugin has any GitHub credentials or endpoint configuration applied
