Can spinning wheels while stuck in the snow damage a CVT?

I pulled over today and the front of my car went into the snow and got stuck. I managed to free myself by shifting into reverse and flooring it for about 30-45 seconds.

Could I have damaged my CVT transmission by doing this? The car in question is a Nissan Maxima.

Also, how can doing something like this potentially damage a CVT transmission? Is the overheating that’s the primary reason for why the damage occurs, or is there something else at play?
