NVD Description

Note: Versions mentioned in the description apply only to the upstream satellite:el8/candlepin package and not the satellite:el8/candlepin package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

Apache Artemis before version 2.52.0 is affected by an authentication bypass flaw which allows reading all messages exchanged via the broker and injection of new message ( CVE-2026-27446 https://www.cve.org/CVERecord ). Since KNIME Business Hub uses Apache Artemis it is also affected by the issue. However, since Apache Artemis is not exposed to the outside it requires at least normal user privileges and the ability to execute workflows in an executor. Such a user can install and register a federated mirror without authentication to the original Apache Artemis instance and thereby read all internal messages and inject new messages.

The issue affects all versions of KNIME Business Hub. A fixed version of Apache Artemis is shipped with versions 1.18.0, 1.17.4, and 1.16.3.

We recommend updating to a fixed version as soon as possible since no workaround is known.
