Subject: CVE-2026-49157: Apache ActiveMQ: Authenticated low-privilege Web
 users retain Jolokia broker-management capability by default 

Severity: important 

Affected versions:

- Apache ActiveMQ (org.apache.activemq:apache-activemq) before 5.19.7
- Apache ActiveMQ (org.apache.activemq:apache-activemq) 6.0.0 before 6.2.6

Description:

Incorrect Default Permissions vulnerability in Apache ActiveMQ.

This issue affects Apache ActiveMQ: before 5.19.7, from 6.0.0 before 6.2.6.

The default Jolokia authorization settings granted non-admin (low-privilege) web-login accounts access to Jolokia operations which allowed executing broker management operations meant for admins such as addQueue and removeQueue.

Users are recommended to upgrade to version 6.2.6 or 5.19.7, which fixes the issue.
