TL;DR The Apache Software Foundation fixed two Apache ActiveMQ vulnerabilities. One lets a low-privilege user bypass write permissions on protected queues. The other lets a remote attacker crash AMQP connections and starve the broker. Why it matters ActiveMQ moves messages between critical business systems. Therefore, broken access control breaks trust across every connected app. Each Apache ActiveMQ vulnerability targets a different layer of the broker.

Shadowserver found more than 6,400 Apache ActiveMQ servers exposed online that are vulnerable to ongoing attacks exploiting a high-severity code-injection flaw tracked as CVE-2026-34197. Discovered by Horizon3 researcher Naveen Sunkavally using the Claude AI assistant after 13 years, the improper input validation bug allows authenticated attackers to execute arbitrary code and was patched in ActiveMQ Classic 6.2.3 and 5.19.4 on March 30; #ApacheActiveMQ #CVE-2026-34197

A remote code execution vulnerability that lurked in Apache ActiveMQ Classic for 13 years can be chained with an older flaw to bypass authentication and force the broker to retrieve and execute remote configuration files via the Jolokia API. Horizon3.ai identifies the issue as CVE-2026-34197, explains it can be combined with...

Security researchers discovered a remote code execution vulnerability in Apache ActiveMQ Classic that went undetected for 13 years and can be exploited to run arbitrary system commands. Tracked as CVE-2026-34197 and found with the help of the Claude AI assistant, the flaw stems from Jolokia’s exposed addNetworkConnector enabling remote Spring XML loading. #ApacheActiveMQ #CVE-2026-34197

CVE-2026-34197 is a critical remote code execution vulnerability in Apache ActiveMQ disclosed in early April 2026. The vulnerability allows an attacker to execute arbitrary code remotely. Specific affected versions and technical details are

TL;DR Apache patched nine Apache ActiveMQ vulnerabilities in version 6.2.7. Most cause denial of service, and several need no login. One flaw lets a connection hijack another connection's temporary destination. Apache reports no in-the-wild exploitation so far. Why It Matters ActiveMQ moves messages for countless Java applications and microservices. Many brokers also sit exposed on the public internet. Past scans found thousands of reachable instances, and attackers have hit ActiveMQ before.
