Unknown Zigbee cluster

I have a Samsung Smarthings plug 2019 with model GP-WOU019BBDWG. I found that it supported an unknwon Zigbee cluster 0xfc82. What is this cluster used for? Do the commands in side the cluster have any security issues?

It’s an inbound cluster, right?

That’s a manufacturer-specific cluster, typically used for some kind of polling, shouldn’t have any more security concerns than any other Zigbee message.
