Security readout for executives and security teams
Plain-English summary
This Jenkins plugin issue could expose GitHub credentials, but only to someone who already has local filesystem access. The main business risk is credential theft leading to GitHub account or repository misuse. The source bundle does not provide a CVSS score, confirmed exploitation, or a named fixed release.
Executive priority
Treat this as important where Jenkins handles valuable GitHub repositories or shared build infrastructure. It is not sourced as actively exploited, but credential exposure can create downstream repository compromise risk.
Technical view
CVE-2018-1000142 affects Jenkins GitHub Pull Request Builder Plugin version 1.39.0 and older. Sensitive GitHub credentials are exposed through GhprbCause.java to an attacker with local filesystem access. The provided evidence does not specify CVSS, CWE, exploit activity, or exact remediation release details.
Likely exposure
Exposure is likely limited to Jenkins environments running GitHub Pull Request Builder Plugin 1.39.0 or older where untrusted users or compromised processes have local filesystem access.
Exploitation context
The source states local filesystem access is required. There is no KEV listing and no provided source claiming active exploitation, public exploit use, or remote unauthenticated attackability.
Researcher notes
Evidence is narrow: affected version, vulnerable component, and local filesystem prerequisite are stated. Missing details include CVSS, CWE, exploit maturity, exact credential storage path, and fixed release. Avoid assuming broader Jenkins or GitHub product impact.
Mitigation direction
- Inventory Jenkins instances for GitHub Pull Request Builder Plugin 1.39.0 or older.
- Review Jenkins SECURITY-261 for vendor-confirmed remediation guidance.
- Restrict local filesystem access on Jenkins controllers and agents.
- Assess whether exposed GitHub credentials require revocation or rotation.
Validation and detection
- Check installed Jenkins plugin versions against version 1.39.0 and older.
- Review Jenkins access controls for local filesystem permissions.
- Audit GitHub credential usage for unexpected repository or account activity.
- Confirm remediation decisions against the Jenkins advisory before deployment.
