AnalysisAI
Authorization bypass in Apache ActiveMQ 5.x before 5.19.9 and 6.x before 6.2.8 allows authenticated low-privilege users to publish messages to any queue without proper write ACLs by abusing temporary composite destinations. This enables unauthorized message injection into restricted queues, potentially disrupting message integrity and business logic. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Requires an authenticated low-privilege user with network access to the broker and the ability to create temporary destinations (default for JMS clients). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The vulnerability requires network access and authentication as a low-privilege user, with no user interaction and low attack complexity. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker with low-privilege authenticated access to the ActiveMQ broker creates a JMS session and constructs a temporary composite destination whose name is a comma-separated list of high-value target queues. They then publish a malicious or spam message to this composite destination; the broker delivers it to all listed queues without verifying write permissions, circumventing ACL restrictions. … |
| Remediation | Upgrade to Apache ActiveMQ 5.19.9, 6.2.8, or 6.3.0, which include the fix. … Detailed patch versions, workarounds, and compensating controls in full report. |
