[Bug]: Player dealing damage to mobs/players in close proximity

What happened?

2 of the players on my server are having problems where they deal damage to any mob or player they walk up to and touch.
I have tried having them empty their inventory and die to make sure no effects/items were in play and it does not seem to fix it.
This have been hapening since before the 2.19 update atleast, i have no idea as of now when the problem started.

Jellyfish curio/artifact/relic does this and could be the cause. It's a light blue necklace that looks like this:

choekstr thanks that is not the cause here tho, the are carrying no items at all and it still causes it.
