Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

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.



This issue affects Apache ActiveMQ Broker: before 5.19.11, from 6.0.0 before 6.3.2; Apache ActiveMQ All: before 5.19.11, from 6.0.0 before 6.3.2; Apache ActiveMQ: before 5.19.11, from 6.0.0 before 6.3.2.



Users are recommended to upgrade to version 6.3.2 or 5.19.11 which fixes the issue.
