I recently purchased two torch corals from a local fish store.
One of them has a small hole in the middle of the Coral with a curious little creature popping out it.
It resembles a feather duster but I’ve never seen one in the middle of a torch Coral

Looks like a coral barnacle.

Is it harmful?

Coral barnacles are interesting and cool looking! I have some vibrant blue ones in my golden Lepthastrea, sadly they only pop out with their fans at night.
