7sleeping can retrieve the answers from the client because the application uses design that leaks answers.
Take this example, a snippet of react code from an imaginary server:
class SecretClass extends React.Component {
constructor() {
super();
this.secret = "SecretPassword!";
}
render() {
return <h2>No one can know my secret!</h2>;
}
}When the render function will be executed, the client will be able to retrieve the whole SecretClass object and its attributes.
>> h2_tag.__reactFiber$1hbspvl3m9b.return.elementType.name
"SecretClass"
>> h2_tag.__reactFiber$1hbspvl3m9b.return.stateNode['secret']
"SecretPassword!" As we can see, using return, we are able to go up the tree and retrieve the initial object SecretClass from the HTML h2 tag.
7sleeping uses a similar approach, retrieving quizz_div.memoizedProps.return.[...].memoizedProps.answerOptions, return is used to go up the object tree until finding the key 'answerOptions', which contain the correct answer.
