{"schemaVersion":3,"id":"CVE-2026-61487","aliases":["UBUNTU-CVE-2026-61487","DEBIAN-CVE-2026-61487"],"status":"published","duplicateOf":null,"title":null,"description":"Improper Authorization vulnerability in Apache ActiveMQ Broker, Apache ActiveMQ All, Apache ActiveMQ.\n\n An authenticated low-privilege user can bypass a per-destination\nwrite ACL by sending to an ActiveMQ temporary composite destination whose physical name is a\ncomma-separated composite of real queues. This allows publishing messages to any of the destinations in the list without proper write ACL permissions because the authorization check is bypassed due to the composite destination being marked as temporary.\nThis issue affects Apache ActiveMQ Broker: before 5.19.9, from 6.0.0 before 6.2.8; Apache ActiveMQ All: before 5.19.9, from 6.0.0 before 6.2.8; Apache ActiveMQ: before 5.19.9, from 6.0.0 before 6.2.8.\n\nUsers are recommended to upgrade to version 5.19.9, 6.2.8 or 6.3.0, which fixes the issue.","dates":{"published":"2026-07-28T13:32:40.768Z","modified":"2026-07-28T14:07:13.139Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":6.5,"severity":"medium","version":"3.1","versionLabel":"v3.1","source":"CVE.org","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":6.5,"severity":"medium","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"OSV
