Ajax question, possible to do data intercepts when response?

[Chrix Wu]

oXHR.onreadystatechange = function() {

    if (oXHR.readyState == 4){
					
     ... do something
    }
};

Is it possible that data gets in here is not the original data sent by backend?

in other words, is it possible someone do any kind of data interceptions when response?

It is an http request so any attacks that would happen with any http post/get applies here.
