About Remote Code Execution - Apache ActiveMQ (CVE-2026-34197) vulnerability. Apache ActiveMQ is a popular open-source message broker written in Java. Its main purpose is to send messages between different services, systems, and microservices without a direct connection between them.

This vulnerability is from the April Linux Patch Wednesday. Details about this vulnerability were published on April 7 in the HORIZON3.ai company blog. They claim that the Apache ActiveMQ Classic vulnerability has been hiding in plain sight for 13 years. An attacker can invoke a management operation through ActiveMQ's Jolokia API to trick the broker into fetching a remote configuration file and running arbitrary OS commands.
