Is a leaking hydraulic log splitter dangerous?

My dad borrowed a hydraulic log splitter to use for firewood. It has a leak in one of the control valves at one of the seals. The leak only occurs when the splitter is hot. The splitter is not well maintained, the company that owns it never changes the oil, and it is left outside to rust. The leak is pretty bad, I would say 4-5 drops per second, and they aren't dropping from the same place. The oil spreads out on the bottom of the valve and drips from multiple locations. I'm concerned that this thing is going to blow and spray high pressure, high temperature hydraulic oil everywhere and hurt somebody. Is this a valid concern? Thanks.
