CVE-2026-40914
Description
A flaw was found in Apache ActiveMQ Artemis (STOMP). An authenticated user with send or consume permission on an address can change that address's routing-type even without createAddress. As a result, send or consume operations that should be rejected for an unsupported routing-type may succeed, undermining address configuration integrity.
Statement
Apache ActiveMQ Artemis is vulnerable to an authorization bypass over STOMP. A network-authenticated attacker with only send or consume rights on an address can augment the address routing-type without createAddress, allowing message send or consume against a routing-type the address should not accept. Fixed in Apache Artemis 2.54.0.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.
