Technical details

This is a stored cross-site scripting (XSS) vulnerability in the Web UI component of IBM Cloud Pak for Business Automation. The vulnerability allows an authenticated attacker to embed arbitrary JavaScript code that persists in the application and executes when other users access the affected UI elements. While authentication is required to inject the payload, the XSS executes in the security context of other users' authenticated sessions, potentially enabling credential disclosure or session hijacking. Fix availability is indicated by the IBM Security Bulletin reference from August 2026.
