CVE-2026-49362: Apache Artemis, Apache ActiveMQ Artemis: Missing Authentication in CORE Protocol Handler Allows Unauthorized Queue Creation

Noroxi assessment

Priority: Monitor (action score 30/100)

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: 0.82% (FIRST EPSS); higher than 57.3% of all records.
Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
According to CISA the attack is automatable: targets can be found by mass scanning.
Fixed version: Apache Software Foundation Apache Artemis 2.57.0.

Low priority for now. Upgrade to Apache Software Foundation Apache Artemis 2.57.0 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

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.
