CVE-2026-40914: Apache Artemis Stomp Protocol, Apache ActiveMQ Artemis Stomp Protocol: Address routing-type can be updated by STOMP protocol user without the createAddress perm

Noroxi assessment

Priority: Monitor (action score 17/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.37% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Apache Software Foundation Apache Artemis Stomp Protocol 2.54.0.

Low priority for now. Upgrade to Apache Software Foundation Apache Artemis Stomp Protocol 2.54.0 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

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. This issue affects Apache Artemis: from 2.50.0 through 2.53.0; Apache ActiveMQ Artemis: from 2.0.0 through 2.44.0. Users are recommended to upgrade to version 2.54.0, which fixes the issue.
