PRODUCT AFFECTED:
This issue affects Apache ActiveMQ Apache ActiveMQ, Apache ActiveMQ Artemis.

PROBLEM:

In this case, for Apache ActiveMQ Artemis prior to version 2.16.0 and Apache ActiveMQ prior to versions 5.16.1 and 5.15.14, the anonymous context is used to verify a valid users password in error, resulting in no check on the password.

This issue is being tracked as https://issues.apache.org/jira/browse/ARTEMIS-2895 and https://issues.apache.org/jira/browse/AMQ-8035.
