High severity GitHub Reviewed Published Jun 1, 2026 to the GitHub Advisory Database • Updated Jul 9, 2026

Package

maven org.apache.activemq:apache-activemq (Maven)

Affected versions

< 5.19.7
>= 6.0.0, < 6.2.6

Description

Incorrect Default Permissions vulnerability in Apache ActiveMQ.

This issue affects Apache ActiveMQ: before 5.19.7, from 6.0.0 before 6.2.6.

The default Jolokia authorization settings granted non-admin (low-privilege) web-login accounts access to Jolokia operations which allowed executing broker management operations meant for admins such as addQueue and removeQueue.

Users are recommended to upgrade to version 6.2.6 or 5.19.7, which fixes the issue.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
