CVE-2026-81207 is a high-severity vulnerability rated 8.5/10 on the CVSS scale. 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. EPSS estimates a 0.22% chance of exploitation in the next 30 days.
