Presumably you can't just nip the wing nut up a bit. If not:
1. Use Screwfix item 517JM. Doesn't matter that it has a rubber washer rather than plastic.
2. Also replace the "doughnut" washer which fits between the cistern where the flush valve is and the bowl.
3. Be prepared to hacksaw the old wing nuts off, they look well and truly rusted on.
4. You will need to:
4.1 Turn the water off to the cistern inlet valve.
4.2 Flush the WC and sponge any remaining water out of the cistern.
4.3 If you are changing the doughnut washer you will need to undo any screws / cut through any silicone securing the cistern to the wall.
4.4 Remove the existing cistern securing bolts. Be careful you don't damage the cistern!
4.5 Remove the cistern from the bowl and clean base of cistern and top of bowl.
4.6 Replace the doughnut washer.
4.7 Replace the cistern securing bolts. If using the Screwfix ones, the conical rubber washers go inside the cistern, with the narrow end pointing down. Tighten the bolts a bit at a time, evenly, so they don't pull the cistern out of level.
4.8. Turn the water back on and make sure nothing is leaking.
4.9 Re-fasten / re silicone the cistern to the wall.

I don't think that has anything to do with cistern fixing bolts. If it was and it uses through the cistern bolts then it would leak anytime the cistern had water in it. If it's leaking only when the toilet flushes then it's probably the cistern to pan doughnut that needs replaced. You will need to take the cistern off to see what type of fixing and doughnut seal it uses to know the correct type to get as there are 2 different types
The through the cistern type bolts with a separate doughnut as above or the captive nut plate type like below with its own doughnut
The fun will certainly be to see if those nuts move or if they'll need cut off. I never pi$$ about and get in there with an angle grinder
