CVE-2026-49157

Apache · ActiveMQ

Incorrect default permissions in Apache ActiveMQ allow low-privilege web-login accounts to perform sensitive administrative operations via Jolokia.

Executive summary

A critical security flaw in Apache ActiveMQ permits low-privilege users to execute unauthorized administrative management operations due to improper default authorization settings.

Vulnerability

The vulnerability stems from incorrect default Jolokia authorization settings. This allows an authenticated, low-privilege user to access and execute management operations—such as adding or removing queues—that are intended exclusively for administrators.

Business impact

With a CVSS score of 8.8, this flaw poses a high risk to message broker integrity. An attacker could disrupt critical business services by manipulating queues or potentially causing a denial of service, leading to significant operational downtime and potential data loss within the messaging infrastructure.

Remediation

Immediate Action: Upgrade Apache ActiveMQ to version 6.2.6 or 5.19.7 to correct the default authorization settings.

Proactive Monitoring: Audit ActiveMQ management logs for unauthorized attempts to invoke management operations from non-admin accounts.

Compensating Controls: Implement strict network-level access controls to limit access to the Jolokia management interface to authorized administrative personnel only.

Exploitation status

Public Exploit Available: false

Analyst recommendation

This vulnerability highlights the danger of overly permissive default configurations. Organizations running Apache ActiveMQ should prioritize updating to the patched versions immediately to prevent unauthorized management of the message broker, which is essential for maintaining system stability and data flow.
