CWE: CWE-502 \u2014 Deserialization of Untrusted Data
The product deserializes untrusted data without sufficiently verifying that the resulting data will be valid.

Code:
	public void processPacket(final EntityPlayer player) {
		if (mode == TargetMode.None) {
			player.addChatMessage(new ChatComponentText(ChatColor.RED + "No Target Found"));
		} else if (mode == TargetMode.Block) {
			int x = (Integer) additions[0];
			int y = (Integer) additions[1];
			int z = (Integer) additions[2];
			player.addChatMessage(new ChatComponentText("Checking Block at: x:" + x + " y:" + y + " z:" + z));
			Block id = player.worldObj.getBlock(x, y, z);
			player.addChatMessage(new ChatComponentText("Found Block with Id: " + Block.getIdFromBlock(id)));
			final TileEntity tile = player.worldObj.getTileEntity(x, y, z);
