Detailsinfo

A vulnerability classified as problematic was found in GoCD up to 26.0.x. This vulnerability affects an unknown function of the file /go/api/admin/internal/material_test of the component Material Test API. The manipulation with an unknown input leads to a privileges management vulnerability. The CWE definition for the vulnerability is CWE-269. The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor. As an impact it is known to affect confidentiality. CVE summarizes:

GoCD is a continuous deliver server. From 16.1.0 until 26.1.0, the internal material connection test APIs at /go/api/admin/internal/material_test and /go/api/internal/config_repos/*/material_test accept an arbitrary existing pipeline and pipeline-group context without sufficient validation. A pipeline group administrator can invoke Test Connection for source control materials outside the administrator's authorized pipeline group or configuration repository and potentially use credentials from those materials. For GoCD 20.6.0 and later, the test context can also resolve external secrets managed by secret-management plugins, including global reusable secrets with separate permissions. This issue is fixed in version 26.1.0.

The advisory is available at github.com. This vulnerability was named CVE-2026-55625 since 06/17/2026. The exploitation appears to be easy. The attack can be initiated remotely. Additional levels of successful authentication are required for exploitation. Successful exploitation requires user interaction by the victim.
