Description
IBM watsonx Orchestrate Cartridge for Cloud Pak for Data 4.8.4 through 4.8.5, and 5.0.0 through 5.4.2 fails to enforce backend authorization checks, allowing low‑privileged users to directly invoke administrative API endpoints. This bypasses UI‑level access restrictions and may lead to unauthorized execution of privileged functions.
