CVE-2025-13691Network attack vector

Authenticated user impersonation via sensitive HTTP response

Published Feb 17, 2026 · Updated Feb 17, 2026

Information exposure in IBM DataStage on Cloud Pak for Data 5.1.2 through 5.3.0 allows remote authenticated users to impersonate other users. The HTTP request-processing path returns sensitive information in a response, but IBM has not identified the endpoint, response field, or triggering request. A valid low-privilege account is required, and the disclosed information enables account impersonation without reported service interruption.
