Summary
Incomplete authorization in Apache ActiveMQ server before versions 6.2.6 and 5.19.7 allows authenticated connections to remove existing destinations with proper permissions.
Risk Assessment
An authenticated attacker can delete queues or topics, disrupting message processing systems and potentially causing data loss.
Recommendation
Upgrade Apache ActiveMQ to version 6.2.6 or 5.19.7.
Other vulnerabilities in Apache ActiveMQ
See all- CVE-2014-3576High
The processControlCommand function in broker/TransportConnection.java in Apache ActiveMQ before version 5.11.0 allows remote attackers to cause a denial of service (shutdown) via a shutdown command.
- CVE-2026-40466High
A vulnerability in Apache ActiveMQ allows an authenticated attacker to bypass the fix for CVE-2026-34197 by adding a connector using HTTP Discovery transport. The attacker can use a malicious HTTP endpoint returning a VM transport, leading to loading a remote Spring XML application context and arbitrary code execution on the broker's JVM.
- CVE-2026-34197HighActively exploited
A vulnerability in Apache ActiveMQ allows an authenticated attacker to achieve remote code execution on the broker via the Jolokia JMX-HTTP endpoint. The attack invokes network connector operations with a crafted URI that loads a remote Spring XML context, leading to arbitrary code execution in the broker's JVM.
- CVE-2015-5254Critical
Apache ActiveMQ 5.x before 5.13.0 does not restrict the classes that can be serialized in the broker, allowing remote attackers to execute arbitrary code via a crafted serialized Java Message Service (JMS) ObjectMessage object.
- CVE-2026-61487Medium
Improper authorization in Apache ActiveMQ allows an authenticated low-privilege user to bypass per-destination write ACLs by sending to a temporary composite destination, bypassing the authorization check.
- CVE-2026-59878High
Apache ActiveMQ (versions before 5.19.9 and 6.0.0 before 6.2.8) has a vulnerability in the AMQP NIO component. A remote unauthenticated attacker can send a frame with a specific size, causing NIO threads to die. Rapid repetition can exhaust the NIO thread pool, leading to denial of service.
- CVE-2026-54475High
A missing authorization vulnerability was found in Apache ActiveMQ for temporary destinations. Temporary destinations are expected to be isolated to the connection that created them, but the isolation is only checked on the client side, allowing a different connection to consume from another connection's temporary destination.
- CVE-2026-53917High
A vulnerability in Apache ActiveMQ allows an authenticated user to cause a DoS attack on the broker by sending a crafted OpenWire message with an excessive map size value. The lack of size validation during deserialization of message property maps can trigger OOM and crash the broker.
- CVE-2026-53916High
A vulnerability in Apache ActiveMQ allows an unauthenticated client to send non-terminating header bytes via STOMP NIO, causing unlimited buffering and JVM heap exhaustion.
- CVE-2026-52760Medium
A Cross-site Scripting (XSS) vulnerability was found in Apache ActiveMQ and its Web Console. The browse page renders a message ID without sanitization, allowing an authenticated producer to send a crafted JMS message ID containing HTML/JavaScript. When an administrator browses the queue, the payload executes in their browser.
Original NVD description (English source)
Incomplete authorization by Apache ActiveMQ server before versions v6.2.6 and v5.19.7 allows authenticated connections to remove existing destinations with proper permissions. This issue affects Apache ActiveMQ Broker: before 5.19.7, from 6.0.0 before 6.2.6; Apache ActiveMQ All: before 5.19.7, from 6.0.0 before 6.2.6; Apache ActiveMQ: before 5.19.7, from 6.0.0 before 6.2.6. Users are recommended to upgrade to version v6.2.6 or v5.19.7, which fixes the issue.
