Title
Unvalidated ZWAVE_CMD_NODES_EXIST May Cause Deletion of End Nodes​
Summary
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.

Drag nodes to arrange them. Double-click a related vulnerability to open it, or a source to visit its link. The Physics button on the left tunes the layout and the simulation; the legend at the bottom left hides or shows nodes by kind and by sighting type.

Forecast uses a logistic model when the trend is rising, or an exponential decay model when the trend is falling. Fitted via linearized least squares.
