Yes, electricity. A corroded connection will have a non-zero
resistance. As current flows through it, the resistance causes the
generation of heat. Enough heat can cause plastic insulation to catch
fire.

There is a huge difference between fresh and saltwater. Until you
have tried to maintain electronics on a boat kept in the ocean you
cannot begin to appreciate the corrosiveness of saltwater.
I have no idea if PowerPoles are more or less likely to succumb to
corrosion and fire than other connectors, but I have no doubt it
could happen.
