Access violation vulnerability in Quiz Maker 6.4.9.4

The Quiz Maker plugin for WordPress has a security issue that allows unauthorized people to access data. This is because a function called ays_quiz_author_user_search does not have a check to make sure only authorized users can use it. This means that hackers who are not logged in can search for users and find their email addresses.
