Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Apache ActiveMQ (including the ActiveMQ Broker and ActiveMQ All packages) is vulnerable in versions before 5.19.6 and from 6.0.0 before 6.2.5. An authenticated attacker who can use the admin web console and message-sending functions can load a remote Spring XML application, which can lead to arbitrary code execution on the broker's JVM. Upgrade to version 5.19.6 or 6.2.5.
