Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Improper validation and restriction of a classpath path name vulnerability in Apache ActiveMQ Client,
 Apache ActiveMQ Broker, Apache ActiveMQ All, Apache ActiveMQ Web, Apache ActiveMQ. In two instances (when
 creating a Stomp consumer and also browsing messages in the Web console) an authenticated user provided
 "key" value could be constructed to traverse the classpath due to path concatenation. As a result, the
 application is exposed to a classpath path resource loading vulnerability that could potentially be
 chained together with another attack to lead to exploit. This issue affects Apache ActiveMQ Client: before
 5.19.3, from 6.0.0 before 6.2.2; Apache ActiveMQ Broker: before 5.19.3, from 6.0.0 before 6.2.2; Apache
 ActiveMQ All: before 5.19.3, from 6.0.0 before 6.2.2; Apache ActiveMQ Web: before 5.19.3, from 6.0.0
 before 6.2.2; Apache ActiveMQ: before 5.19.3, from 6.0.0 before 6.2.2. Users are recommended to upgrade to
 version 5.19.4 or 6.2.3, which fixes the issue. Note: 5.19.3 and 6.2.2 also fix this issue, but that is
 limited to non-Windows environments due to a path separator resolution bug fixed in 5.19.4 and 6.2.3.
 (CVE-2026-33227)

Solution

Update the org.apache.activemq:activemq-all library and its related packages to version 5.19.3 or later.
