DescriptionIBM MQ Agent CD: v1.0.0, v1.0.1, v2.0.0, v2.0.1 An authenticated user with a valid session cookie can submit arbitrarily large or computationallyexpensive requests that cause the LLM agent workers to be held for extended periods — rangingfrom tens of seconds to over ten minutes per request. When multiple such requests are sentconcurrently, the agent worker pool becomes exhausted, causing all other IBM MQ Console users toexperience degraded performance or complete unavailability of the AI Agent feature.
