ActiveMQ Jolokia Default Permissions Grant Admin Access to Low-Privilege Users

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.

Casky was already ahead

This CVE exploits attack patterns that Casky's 203matched skills already investigate — long before this vulnerability was disclosed. Claude's reasoning model maps these techniques to MITRE ATT&CK, so practitioners who ran these skills have already seen the threat behaviour in their findings.

Analysis

CVE-2026-49157 represents a critical privilege escalation vulnerability in Apache ActiveMQ where default Jolokia authorization settings fail to properly restrict administrative operations. Low-privilege web-login accounts can access Jolokia endpoints that should be reserved for administrators, enabling them to execute sensitive broker management operations including addQueue and removeQueue. This vulnerability affects ActiveMQ versions before 5.19.7 and 6.0.0 through 6.2.5, making it a widespread risk for organizations deploying these versions. The impact is significant because it allows attackers with basic web access to manipulate message queue infrastructure, potentially disrupting operations, exfiltrating data, or establishing persistence through unauthorized queue manipulation.

Casky.ai's 203 mapped skills detect the attack patterns underlying this vulnerability by analyzing MITRE ATT&CK technique TA0004 (Privilege Escalation) through Claude's extended reasoning capabilities. Practitioners would identify suspicious patterns such as low-privileged users invoking Jolokia admin operations (detected via HTTP request analysis to Jolokia endpoints), unauthorized queue creation or deletion activities, and role-permission mismatches in access logs. The platform correlates default configuration analysis—identifying when Jolokia authorization policies lack proper role-based access controls—with behavioral indicators like unexpected administrative API calls from standard user accounts. Security teams would see findings highlighting insecure default configurations, the absence of granular permission boundaries, and unusual privilege escalation attempts that deviate from normal ActiveMQ administration patterns.
