Insecure server events allow anyone to spawn in free money

[j-mie]

RegisterServerEvent('esx_vangelico_robbery:gioielli')
AddEventHandler('esx_vangelico_robbery:gioielli', function()
	local xPlayer = ESX.GetPlayerFromId(source)
	xPlayer.addInventoryItem('jewels', math.random(Config.MinJewels, Config.MaxJewels))
end)

RegisterServerEvent('lester:vendita')
AddEventHandler('lester:vendita', function()

	local _source = source
	local xPlayer = ESX.GetPlayerFromId(_source)
	local reward = math.floor(Config.PriceForOneJewel * Config.MaxJewelsSell)

	xPlayer.removeInventoryItem('jewels', Config.MaxJewelsSell)
	xPlayer.addMoney(reward)
end)

Anyone can fire these events without it even checking if they're started a robbery, leading to free money and ruined economies.
