Source description

As published by the source; long descriptions are shortened.

Jenkins Team Concert Plugin 1.3.0 and earlier does not perform permission checks on a method implementing form validation. This allows users with Overall/Read access to Jenkins to connect to an attacker-specified URL using attacker-specified credentials IDs obtained through another method, capturing credentials stored in Jenkins. Additionally, the form validation method does not require POST requests, resulting in a CSRF vulnerability. As of publication of this advisory, there is no fix.

# Patch Next advisory brief: CVE-2019-16566

Advisory: Jenkins Team Concert Plugin missing permission check
IDs: CVE-2019-16566, GHSA-c998-c4f6-vjw2
Record: https://patchnext.com/advisories/cve-2019-16566 (revision 1, source checked 26 Oct 2026, 16:15 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 7.1)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor response not established. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven org.jenkins-ci.plugins:teamconcert: affected <= 1.3.0

## Suggested inspection (read-only)
- Maven org.jenkins-ci.plugins:teamconcert: check the installed version with your package manager.

## Supported action
No complete vendor fix is recorded. Follow the primary source's mitigation guidance and check this record again before closing anything.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on org.jenkins-ci.plugins:teamconcert.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
