Large tables in data apps can bring down execution services in KNIME Hub
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.
