It's odd that it starts leaking after the oil changed. The engine oil filter is on the side of the engine facing toward the front of the vehicle, so in my mind, they shouldn't be hitting the hoses. However, anything is possible. I attached a pic below showing the location of the oil filter. Check around that area to see if you notice any hoses leaking.
Next, the idea that it drains overnight leads me to believe it is the low-pressure return line. If the high-pressure hose was faulty, it would be spraying when the engine is running. I attached a pic below showing both power steering hoses. I highlighted the low-pressure hose, so see if you can follow that.
As far as access, since you are working outside, I would safely lift the right front tire off the ground and remove it. You should be able to see the rack from that point.
Let me know what you find.
