Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Apache ActiveMQ Broker, Apache ActiveMQ All, and Apache ActiveMQ before 5.19.7, and from 6.0.0 before 6.2.6, are affected. An authenticated attacker can bypass the earlier fix for CVE-2026-34197 using crafted discovery configuration, which can lead to code execution on the broker's JVM. Upgrade to 5.19.7 or 6.2.6.
