Replace the quick releases - I wouldn't ride that until you have, as
@ColinJ says the front wheel is not secured anymore - the cam mechanism which holds the wheel tight against the frame is no longer present. It's probably been overtightened and failed.
You can remove the existing one by putting a screwdriver through the hole and holding the nut on the other end it should unscrew quickly.
I'd get a decent quick release - I tend to find Shimano ones to be the best, you can get cheaper ones, but they use an open cam which whilst saving you a couple of grams in weight degrades quite quickly and then struggles to provide a strong clamping force.
