## Summary

Software: IBM watsonx Orchestrate Cartridge for Cloud Pak for Data, which includes the watsonx Assistant cartridge. An attacker with a low-privileged account can reach it remotely over the network and directly call administrative API endpoints, which skips the access restrictions enforced in the user interface, and so may carry out privileged functions they should not be able to run. The flaw is in the backend, which does not check authorization for these endpoints.

## Affected

- IBM watsonx Orchestrate Cartridge for Cloud Pak for Data: from 4.8.4, through 4.8.5; from 5.0.0, through 5.4.2

## Description
