CVE-2026-54475: CWE-862 Missing Authorization in Apache Software Foundation Apache ActiveMQ Broker
Missing Authorization vulnerability in Apache ActiveMQ Broker, Apache ActiveMQ All, Apache ActiveMQ. Apache ActiveMQ Classic temporary destinations are expected to be isolated to the connection that created them. The isolation can be broken as this is only checked in the client, allowing a different connection to consume from another connection's temporary destination. This issue affects Apache ActiveMQ Broker: before 5.19.8, from 6.0.0 before 6.2.7; Apache ActiveMQ All: before 5.19.8, from 6.0.0 before 6.2.7; Apache ActiveMQ: before 5.19.8, from 6.0.0 before 6.2.7.

AI Analysis
Technical Summary
The vulnerability in Apache ActiveMQ Broker (CVE-2026-54475) is a missing authorization issue (CWE-862) where temporary destinations, intended to be isolated per connection, can be accessed by different connections. This occurs because the isolation enforcement is only done on the client side, allowing unauthorized consumption from another connection's temporary destination. The affected versions include all versions before 5.19.8 and versions from 6.0.0 up to 6.2.7. The vendor recommends upgrading to version 6.2.7, which fixes the issue.
Potential Impact
Unauthorized connections can consume messages from temporary destinations created by other connections, potentially leading to unauthorized data access within the messaging system. This breaks the expected isolation model of temporary destinations in Apache ActiveMQ Broker.
Mitigation Recommendations
Users should upgrade Apache ActiveMQ Broker to version 6.2.7, which contains the fix for this missing authorization vulnerability. No other mitigation or temporary workaround is indicated in the available data.
