Coolant in spark plug all 4 cylinders

Check or change your oil and see if there’s coolant in it.
You’re positive it’s coolant?
Which cylinders can you confirm has coolant?

checked coolant level in the radiator? don't trust the overflow.
pressure test the cooling system, maybe some pinhole somewhere is spraying coolant like crazy? seems so odd to have coolant in all 4 plug holes though.....

Cracked head is the only possibility.
If these symptoms are accurately described my wild butt guess is this car saw a winter with less than necessary coolant concentration, froze internally, and cracked the heads.
And you it recently saw some major circumstance like You just bought it, it had major work, etc....
When did you buy this car?
Has it ever had major work?
Is there any chance the coolant concentration was wrong or never monitored?
There’s no way for coolant to otherwise get to all the spark plug tubes. And it would be impossible for both to do it, and at the exact same time.

Id test for cracked heads first.
Having never seen or heard of this before here’s my suggestion:
Remove the plugs and wires and then pressure test the cooling system and watch the spark plug tubes to see if they take in coolant.
Review the paperwork on the radiator.
Radiator replaced in April - which means something was leaking or overheating before that and they tried to replace the radiator to fix it. the radiator was replaced and then the car wasn’t driven again until sold. They ditched the car after the radiator didn’t fix it.
Anyway - at some point there was too much water in the system and it froze and cracked the heads. Which isn’t surprising someone got stuck or desperate and filled with water to get home or drive to work and left it without checking it. Then it froze. Or worse it was leaking coolant - as it currently is - and the previous owner let it get so low that it overheated significantly and blew the heads. This seems unlikely for a few reasons so I’m betting on freezing.

No other way for there to be a noticeable amount of coolant in the plug tubes without there being huge amounts of it in the rest of the engine oil as well.

Fairtax beat me to it. Old radiator, or possibly a hose, etc. let go, and there was residual coolant everywhere, that probably coated the underside of the hood and engine, and whatever didn't wash away is what you are finding. If it was an inline engine, might be a different story.
To be safe though, watch everything like a hawk for awhile. Everything from oil level, coolant level, engine temps, etc. and pay attention if it starts loosing power, making odd sounds, etc. and go from there?
