This is a potential issue for every mutable object. For immutable objects, you don't need to worry about it. They can be accessed from outside, but they cannot be modified anyways. For mutable objects, this is a problem. And whenever an object is extra sensitive or extra accessible, you'll have to create deep copy before returning the object.
