It's hard to say what happened, but you need more observation to narrow it down. You did not say if the fluid level is down. Have you been paying attention to the fluid level? Any sign of leaking at the master cylinder or at the bottom of any of the backing plates? These areas are supposed to be dry.

I had a similar thing happen. I got in the car, and the pedal went to the floor. I checked the fluid level and it was empty. Checked the garage floor and all the fluid was on the floor under the master. All wheel cylinders were leak free. The entire leak was past the master cylinder cup. I refilled the master, and the problem never showed again. That was ten years ago. I use silicon DOT5, and I suspect there was some particle that ended in the wrong place and allowed the leak over an extended period of time, until it went dry.
