CVE-2026-49270: Apache ActiveMQ Broker, Apache ActiveMQ, Apache ActiveMQ All: Durable Subscription Disclosure via Crafted BrokerInfo (OpenWire)

Noroxi assessment

Priority: Monitor (action score 23/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.36% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. Special conditions such as timing or configuration are required.
  • Fixed version: Apache Software Foundation Apache ActiveMQ 5.19.7, 6.2.6; Apache Software Foundation Apache ActiveMQ All 5.19.7, 6.2.6; Apache Software Foundation Apache ActiveMQ Broker 5.19.7, 6.2.6.

Low priority for now. Upgrade to Apache Software Foundation Apache ActiveMQ 5.19.7, 6.2.6; Apache Software Foundation Apache ActiveMQ All 5.19.7, 6.2.6; Apache Software Foundation Apache ActiveMQ Broker 5.19.7, 6.2.6 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

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.
