Summary

IBM MQ Agent CD versions v1.0.0, v1.0.1, v2.0.0, v2.0.1 allow an authenticated user with a valid session cookie to submit arbitrarily large or computationally expensive requests that hold LLM agent workers for extended periods — from tens of seconds to over ten minutes per request. When multiple such requests are sent concurrently, the agent worker pool becomes exhausted, causing all other IBM MQ Console users to experience degraded performance or complete unavailability of the AI Agent feature.

Risk Assessment

The risk includes the possibility of a DoS attack on the AI Agent feature, which can disrupt user operations and impact service availability.

Recommendation

It is recommended to implement limits on request size and complexity, monitor resource usage, and apply patches from IBM.
