Is it possible for a player to change the data within in a module Script from the client and affect the server? Lets say module is

ItemPrices = {100, 200, 300}
return ItemPrices

For example lets say the price of an item is stored in a module script. If an exploiter would change the price of that item in the module script on the client side lets say running a script with the following code:

require(game.ReplicatedStorage.ItemPrices)[1] = 0

Would that change the value of the module script on the server side? Or only for the players client? For example right after the exploiter runs that script lets say I were to print on the server the price of Item 1. Would it print 100 or 0?
