CVE-2023-50959Network attack vector

Authenticated document disclosure via system-account queries

Published Mar 31, 2024 · Updated Aug 2, 2024

Information disclosure in IBM Cloud Pak for Business Automation allows remote authenticated users to read unauthorized ECM documents. The Business Automation Workflow document-query path uses a configured system account in a way that returns documents outside the end user's expected result scope; IBM has not disclosed the responsible function. Exploitation requires an authenticated end user and a connected Enterprise Content Management system configured with a system account; the reported consequence is document disclosure only.
