CVE-2026-4649 Details
Description
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.
A vulnerability exists in KNIME Business Hub versions prior to 1.18.0, stemming from an authentication bypass flaw in the Apache Artemis messaging broker it uses. This vulnerability allows users with normal privileges and the ability to execute workflows to read all internal messages exchanged via the broker and inject new messages. The issue arises because Apache Artemis is not exposed externally, requiring at least normal user privileges to exploit. Affected users can install and register a federated mirror without authentication, gaining access to internal messages and the ability to inject new ones.
Users are advised to update to KNIME Business Hub versions 1.18.0, 1.17.4, 1.16.3, or 1.15.2, all of which include the patched version of Apache Artemis.
