As you can see, the Top 10 list from Firehound has lots of AI apps. The project claims all kinds of data, from email addresses, to chat history, to names were left accessible by apps. One would hope that apps would work to fix such vulnerabilities moving forward, should they exist.
Moving forward, it's probably best for users to tread carefully when downloading an app. It's worth stopping to think if it's a trustworthy product. And, of course, it's probably worth being cautious when sharing personal or professional information with an AI chatbot. You never know if it'll become public.
