Description
IBM DataStage on Cloud Pak for Data 5.4.0.0 allows any authenticated tenant — with no project membership or role — fully controls scheme/host/port/path of an outbound fetch originating from a shared-infrastructure pod, and the WSDL body is reflected verbatim to the caller. The ds-canvas pod sits on the OpenShift overlay with reach to co-tenant services, in-cluster CP4D APIs, and link-local addresses. Scope is Changed, confidentiality High (response-reflecting), integrity Low (GET-only side-effects).
