Official description
KNIME Business Hub is affected by the Ingress-nginx CVE-2025-1974 ( a.k.a IngressNightmare ) vulnerability which affects the ingress-nginx component. In the worst case a complete takeover of the Kubernetes cluster is possible. Since the affected component is only reachable from within the cluster, i.e. requires an authenticated user, the severity in the context of KNIME Business Hub is slightly lower. Besides applying the publicly known workarounds, we strongly recommend updating to one of the following versions of KNIME Business Hub: * 1.13.3 or above * 1.12.4 or above * 1.11.4 or above * 1.10.4 or above *

The underlying weakness: Improper Control of Generation of Code
The product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment.
How developers prevent this class of flaw
- Refactor your program so that you do not have to dynamically generate code.
- Run your code in a jail or similar sandbox environment that enforces strict boundaries between the process and the operating system. This may effectively restrict which code can be executed by your product. Examples include the Unix chroot jail and AppArmor. In general, managed code may provide some protection. This may not be a feasible solution, and it only limits the impact to the operating system; the rest of your application may still be subject to compromise. Be careful to avoid CWE-243 and other weaknesses related to jails.
- Use dynamic tools and techniques that interact with the product using large test suites with many diverse inputs, such as fuzz testing (fuzzing), robustness testing, and fault injection. The product's operation may slow down, but it should not become unstable, crash, or generate incorrect results.
