Official description

GoCD is a continuous deliver server. Prior to 26.1.0, GoCD can return unmasked credentials that administrators stored in the userinfo portion of source control material URLs through several read-only APIs available to regular authenticated users. Although GoCD recommends dedicated username and password fields or secret-management plugins, legacy configuration permits credentials in material URLs, and not every mixed-use API consistently applies URL masking for every material type. An authenticated user with access to an affected pipeline can obtain credentials embedded in its material URL, while dedicated password fields remain encrypted and are not exposed by this issue. This issue is fixed in version 26.1.0.
