Unvalidated ZWAVE_CMD_NODES_EXIST May Cause Deletion of End Nodes
In Z-Wave SDK 8.1.1 and earlier (for 700/800 series devices) and 6.85.02 and earlier (for 500 series devices), missing checks in the ZWAVE_CMD_NODES_EXIST handler can result in nodes being removed from the network. These messages must come from a device that has already joined the network.
