I can't think of a reason it'd be any more dangerous than if the same food was sitting on your counter for the same time period. But some people won't eat cold pizza that sat out overnight either.
When we can food, sometimes there's a jar that doesn't seal. We just put it in the fridge and use it in the next few days. It'll keep at least as long as if it hadn't been canned.
Having said all that: if I went to open a can of food and saw that it had a leak, I wouldn't eat it, because how could I be sure that it wasn't leaking when I packed it 24 hours ago? A visible leak now might have been too small to see then, so who knows how long it's really been leaking.
A pinhole means low oxygen + outside contact which means botulism, which only thrives in almost sealed environments. Botulism toxins kill. Moreso than many other ways your food can spoil open to the air.
Rust develops much faster on a boat at sea. A breach from rust can affect a can with enough botulism toxin to have bad effects within 3-4 days. Most cans probably have a plastic liner though but I'm not sure how much of a safeguard it is.
