{"id":"CVE-2026-40914","aliases":["GHSA-rf99-f9j2-gv3f"],"url":"https://o3.security/vulnerability/CVE-2026-40914","summary":"Apache Artemis Stomp Protocol, Apache ActiveMQ Artemis Stomp Protocol: Address routing-type can be updated by STOMP protocol user without the createAddress permission","details":"A vulnerability exists in Apache Artemis whereby an application using the STOMP protocol with security credentials that grant either the consume or send permission on an address can augment the routing-type supported by that address even if said user doesn't have the createAddress permission for that particular address. A user could successfully send a message to an address or consume a message from a queue with a routing-type not supported by the corresponding address when that operation should actually be rejected on the basis that the user doesn't have permission to change the routing-type of the address. Even though the user was already granted permission to send and/or consume messages, they should not be able to augment the routing-type of the address without the createAddress permission.\n\n\n\nThis issue affects Apache Artemis: from 2.50.0 through 2.53.0; Apache ActiveMQ Artemis: from 2.0.0 through 2.44.0.\n\nUsers are recommended to upgrade to version 2.54.0, which fixes the issue.","published":"2026-05-28T12:28:25.972Z","modified":"2026-08-12T03:51:23.910971029Z","cvss":{"score":4.3,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N"},"epss":{"score":0.00372,"percentile":0.29892,"asOf":"2026-08-24"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Maven","name":"org.apache.artemis:artemis-stomp-protocol","fixedVersion":"2.54.0"},{"ecosystem":"Maven","name":"org.apache.artemis:artemis-stomp-protocol","fixedVersion":null}],"fix":null,"references":[{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2026/05/27/8"},{"type":"WEB","url":"https://repo.maven.apache.org/maven2"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/40xxx/CVE-2026-40914.json"},{"type":"ADVISORY","url":"https://lists.apache.org/thread/6q3st8dlorz2q05svqn11k1xl7jkmm4c"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-40914"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:23.910971029Z"}}
