High [CVE-2026-49362] artemis core protocol permits unauthed queue creation
CVE-2026-49362Source published Source updated
An unauthenticated remote attacker can create arbitrary durable queues via the CORE protocol, leading to unauthorized broker state manipulation and potential denial of service. This issue affects Apache Artemis: from 2.50.0 through 2.56.0; Apache ActiveMQ Artemis: from 1.0.0 through 2.44.0. Users are recommended to upgrade to version 2.57.0, which fixes the issue. Artemis CORE protocol channel allows unauthed queue creation. an unauthenticated attacker can send CREATE_QUEUE packets on channel 1 via the:8080 HTTP-upgrade path to create arbitrary durable JMS queues on the embedded broker. This can be used for resource exhaustion and persistent broker-state manipulation. Red Hat severity: Important — CVSS 8.2 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:H). Weakness: CWE-306.
