Threat database

When used as an executor in either KNIME Server or KNIME Business Hub, KNIME Analytics Platform LTS versions before 5.8.4 log configured credentials of proxies during startup. An attacker with access to log files can steal the credentials and use the proxy as the user who configured the proxy settings. The issue has been fixed in LTS versions 5.8.4 and 5.12.0 and later.

KNIME Business Hub versions before 1.19.0 have a vulnerability where sensitive cookies used in HTTPS sessions lack the 'secure' attribute. This omission can allow an unauthenticated remote attacker to compromise user sessions if combined with other security issues like cross-site scripting or man-in-the-middle attacks. No workaround is available for this vulnerability.

CVE-2026-115517 is a vulnerability in KNIME Business Hub versions before 1.19.0 that allows unrestricted network access between execution contexts. An authenticated remote user can access open network ports on executors in different execution contexts if the attacked executor's IP address is known and ports are open without further authentication. By default, no network ports are open, but workflows may open ports, creating an attack surface. Manual network policies can mitigate this risk.

A missing authorization check allows anyone having access to a "link without login" for a DataApp to list and potentially access jobs of other users created by the same link in KNIME Business Hub prior to 1.19.0. As workaround remove all "links without login" to DataApps.

Overly informative error messages in the catalog functionality of KNIME Business Hub prior to version 1.18.5 may allow an authenticated remote attacker to see workflow names if their ID is known. A workaround is not possible.

A flaw in the cross-site request forgery (CSRF) prevention of KNIME Business Hub prior to version 1.19.0 allows an authenticated attacker to perform a CSRF attack with passive user interaction. This means the state of a resource could be changed without the user noticing. As a workaround, an API gateway for firewall in front of KNIME Business Hub could remove the X-Forwaded-For header from all incoming requests.

An excessive resource allocation issue in the remote workflow editing capabilities of KNIME Business Hub prior to version 1.19.0 allows a authenticated attack to exhaust resources on the server side. This leads to intermittent unavailability of workflow execution functionality. A workaround is not possible.

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 wrong permission check in KNIME Business Hub before version 1.17.0 allowed an authenticated user to save jobs of other users as if there were saved by the job owner. The attacker must have permissions to access the jobs but then they were saved into the catalog service using the wrong owner permissions. Therefore it may have been possible to save into spaces where the attacker does not have write permissions. There is no workaround.

An open redirect vulnerability existed in KNIME Business Hub prior to version 1.16.0. An unauthenticated remote attacker could craft a link to a legitimate KNIME Business Hub installation which, when opened by the user, redirects the user to a page of the attackers choice. This might open the possibility for fishing or other similar attacks. The problem has been fixed in KNIME Business Hub 1.16.0.

Potentially sensitive information in jobs on KNIME Business Hub prior to 1.16.0 were visible to all members of the user's team. Starting with KNIME Business Hub 1.16.0 only metadata of jobs is shown to team members. Only the creator of a job can see all information including in- and output data (if present).
