affected by a spoofing vulnerability:

  - Improper input validation in TopicRegion in Apache ActiveMQ, Apache ActiveMQ Broker, and Apache ActiveMQ All on all
    platforms. An authenticated client can spoof clientId when removing a durable topic subscription.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
