You can be attacked through a palisade.

I'm assuming it's something to do with he hit boxes size, was ranging a boar from inside my palisade, stood right next to the pali so i'm as close as can be, boar deals 27 damage.

the boar fleed when I damaged it, i'll try get a screeny if another one comes close by.

Edit:

-snip- stood right next to the pali so i'm as close as can be -snip-

that's why ... step a tile away from Pali and they won't hurt you - no bug

Yeah I figured that, however i assumed it was a bug, wouldn't make sense for a boar to be able to hit you through a wall.

I killed 2 people through a fence without a gate (had trespassing and rage, they were stupid enough to log off right next to fence)
Important info:
They stole my meat grinder and destroyed it while I was watching.
