Just happened to me, I play on the server, DayZ US - NY 6053 (1st Person only). Exact 7 cuts. I have barbed wire on both slots of the gate and while issuing the code for the code lock i turned to check the character blind spot, i usually do this so i dont get shot at while entering my base. 1st digit went fine (i hadn't turned my character yet). 2nd digit as soon as i turn my character, i get 2 cuts, then walk away and cuts start increasing up to 7, constantly issuing the cut/damage sound and animation. I was alone and couldn't bandage due to being constantly interrupted, saline bag couldn't be used as well.
