If you are an admin, give them a formal warning, if they continue to vandalize, block them. If you're not an admin and no admin on that wiki hasn't addressed the vandal yet, then give an admin the edit history on your talk page to show them and let them decide depending on your wiki policies there. I hope you have reverted the vandalism since the edit too.
