Security readout for executives and security teams
Plain-English summary
Jenkins DotCi Plugin can store and later display unsafe GitHub user-name content in build-cause information. If an exposed Jenkins instance uses DotCi Plugin 2.40.00 or earlier, a user viewing affected build details could have script run in their browser.
Executive priority
Treat as a moderate application-security issue. It is not shown as actively exploited, but Jenkins is operationally sensitive, and stored XSS can affect trusted users who manage builds and delivery workflows.
Technical view
CVE-2022-41239 is a stored XSS issue in Jenkins DotCi Plugin 2.40.00 and earlier. The plugin fails to escape the GitHub user name parameter in commit notifications when rendering build causes. The CVSS vector indicates network reachability, low privileges, required user interaction, changed scope, and limited confidentiality and integrity impact.
Likely exposure
Exposure is limited to Jenkins environments with DotCi Plugin 2.40.00 or earlier installed. Risk is higher where commit notifications include GitHub identity data and Jenkins users routinely view build cause details.
Exploitation context
The bundle provides no evidence of CISA KEV listing or active exploitation. Exploitation requires a stored malicious value and a user viewing the affected Jenkins build-cause display, based on the CVSS user-interaction requirement.
Researcher notes
Key uncertainty is remediation status: the supplied bundle names affected versions but does not name a fixed release or mitigation. Analysis should stay tied to Jenkins advisory SECURITY-2884 and avoid claiming exploit activity without additional cited evidence.
Mitigation direction
- Inventory Jenkins controllers for DotCi Plugin installations and versions.
- Review Jenkins advisory SECURITY-2884 for current vendor remediation guidance.
- Do not assume a fixed version from this bundle; verify with Jenkins sources.
- Prioritize remediation for Jenkins instances accessed by many developers or administrators.
Validation and detection
- Confirm whether DotCi Plugin is installed on each Jenkins controller.
- Record the installed plugin version and flag 2.40.00 or earlier.
- Review vulnerable build-cause display paths for exposure to commit notification data.
- Check vulnerability tracking for remediation evidence tied to Jenkins advisory SECURITY-2884.
