CVE-2026-55625

4.9 MEDIUM 0.6% exploit odds Fix listed Auth & access Server

What it is

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.
