AnalysisAIv1 – Sep 15, 2026

An XPath injection flaw (CWE-643) in IBM Cloud Pak for Business Automation lets an authenticated user manipulate XPath queries and read data the query engine should never return, including sensitive application records and structural details of the underlying XML documents. All shipped 24.0.x, 25.0.0 and 26.0.0 streams are affected up to and including Interim Fix 001/005/008/009 respectively, and exploitation only requires a low-privileged, network-reachable session — no user interaction and no special complexity. IBM has published a vendor fix; there is no CISA KEV listing and no public exploit code identified at time of analysis, so this is currently a patch-on-schedule issue rather than an emergency.
