Can someone help explain how a closed soda can rupture from a pin hole?

I left my sodas in the garage, in the heat. I know that was a big mistake but as soon as I started to move some they started spewing soda from the side of the can. Only 3 of them did that. Does that mean that someone might’ve injected something on the side of it. I’ve only seen sodas rupture from the pressure on the top of the can where it opens when it is left in the freezer. Or are they designed to do this in high heat to keep from exploding?
Do you think any of them are safe to drink? Or is it just from the heat.
