Doc Text:	A flaw was found in Apache ActiveMQ. An unauthenticated attacker can exploit this vulnerability when brokers are configured with a network connector with syncDurableSubs set to true. By sending a BrokerInfo command, the attacker can receive a list of all durable topic subscriptions, including sensitive details like client identifiers, subscription names, topic destinations, and JMS selector expressions. This information disclosure is due to the broker incorrectly responding without first ensuring the connection is authenticated.	Story Points:	---

Description OSIDB Bzimport 2026-06-09 08:57:54 UTC

Exposure of Sensitive Information Through Metadata vulnerability in Apache ActiveMQ Broker, Apache ActiveMQ, Apache ActiveMQ All.

Brokers that are configured with a network connector with syncDurableSubs set to true, are vulnerable to an unauthenticated attacker who can receive a list of all durable topic subscriptions in the broker, including client identifiers, subscription names, topic destinations, and JMS selector expressions, by sending a BrokerInfo command. The broker incorrectly responds without first ensuring the connection is authenticated.
This issue affects Apache ActiveMQ Broker: 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; Apache ActiveMQ All: before 5.19.7, from 6.0.0 before 6.2.6.

Users are recommended to upgrade to version 6.2.6 or 5.19.7, which fixes the issue.
