Definitely external. There’s nothing under those parts that could produce that kind of heat.
It seems like heat was focused onto that spot. That’s unfortunate.
My CR-V handled 120-degree temps in Phoenix, so I think this has to be vandalism, like someone really used a propane torch.

Sunlight focused by reflections can easily exceed that temperature without an actual flame.
A torch would be tough to use without damaging the plastic in some way.
