Is TestWhiz: AI for quizzes and assignments 📚 safe?
TestWhiz listens for a page-posted LOGIN_SUCCESS message with no origin check and stores the supplied userId on every site.
TestWhiz's content script runs on all websites and accepts a window postMessage of type LOGIN_SUCCESS from any page, without checking who sent it. Whatever userId value the message carries is passed to the background script and saved, then attached to every screenshot and question the extension later sends to api.testwhiz.co. This means any web page a user visits could set the ID linked to their extension activity.
