Check your water supply connections and tighten them as needed, first.
After that, I would suspect and just plan on replacing the toilet's seal, either wax or wax-free are perfectly fine. This, is actually fairly easy and quick to do.
Sound like a leap? Well, doing so may reveal the seal to be the actual problem, but also force you to assess the entire toilet in wrestling it.
If you have a 2-piece toilet, the leak could be coming from failing bolt washers in the bottom of the tank or a failing tank to bowl gasket under the tank. Is your tank loose and wobbly? A good chance that the water's coming from the tank connections that need to be tightened.
A final item is the fill valve and even specifically the bowl filling tube. The valve may be spraying the tank lid or the bowl filler may have come loose and is spraying the lid.
Like above, water may be finding the toilet's exterior and just running down to the base periodically.
