What is CVE-2026-55625?

GoCD, a continuous delivery server developed by ThoughtWorks, has a vulnerability in its internal material connection test APIs. Versions from 16.1.0 to 26.1.0 suffer from inadequate validation, allowing administrators of a pipeline group to invoke Test Connection for source control materials that lie outside their authorized context. This could lead to unauthorized access to sensitive credentials associated with external secrets, including those managed by secret-management plugins. This issue was rectified in the GoCD 26.1.0 release.

Affected Version(s)

gocd >= 16.1.0, < 26.1.0
