AnalysisAI
Denial of service in Apache ActiveMQ Artemis and Apache Artemis message brokers allows authenticated clients holding MANAGE permission to crash broker processing threads by submitting crafted management-via-messaging requests that trigger unsafe Java deserialization. The deserializer processes method parameters the broker never actually uses, permitting gadget-chain payloads that consume excessive CPU and pin the thread pool. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires three concurrent conditions: (1) the attacker must hold a valid authenticated session on the Artemis broker - anonymous or unauthenticated connections cannot trigger this path; (2) that account must be granted the MANAGE permission specifically, which controls access to management-via-messaging operations and is a privileged ACL entry distinct from standard SEND/CONSUME rights; (3) management-via-messaging must be enabled on the broker (it is the default, but can be disabled). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Real-world risk is moderate. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Upgrade to Apache ActiveMQ Artemis 2.57.0, which was released on September 9, 2026, and directly addresses this issue per the vendor's release notes at https://artemis.apache.org. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, identify all deployments of Apache ActiveMQ Artemis (versions 1.3.0-2.44.0) and Apache Artemis (versions 2.50.0-2.56.0) in your environment and enumerate accounts with MANAGE permissions. …
