CVE-2018-1000186
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 · uneditedA 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 confidenceThe 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.

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 checksWork through these to decide whether this CVE applies to you.
-
Verify plugin versionNavigate to Manage Jenkins > Manage Plugins > Installed tab, locate 'GitHub Pull Request Builder' (ghprb) plugin, and check the Version columnAffected if Version listed is 1.41.0 or lower (or if version cannot be determined but plugin is present and older)
-
Confirm plugin is configuredNavigate to Manage Jenkins > Configure System > find 'GitHub Pull Request Builder' section. Check if any GitHub API credentials or server URL are configuredAffected if Plugin has any GitHub credentials or server URL configured and the plugin version is vulnerable
-
Review credential usageNavigate to Manage Jenkins > Credentials > review any credentials with 'ghprb' or 'GitHub Pull Request Builder' in the description or tied to the plugin's scopeAffected if Credentials exist that were used by the vulnerable plugin configuration
-
Check for external endpoint configurationIn the plugin configuration (Configure System > GitHub Pull Request Builder), examine the 'GitHub Server URL' and any override settings for repository webhooksAffected 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

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpgrade 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.
