It works. That does not mean it is safe.
It took one person a few hours to find sixteen security holes, six of them critical, in an education app that Lovable had shown as an example of what its tool can build. They shared the results on Reddit. Records for 18,697 users were open to anyone, including student grades, and a stranger could delete accounts or change grades without logging in. The app worked perfectly for its real users the whole time.
This is the main risk with apps built by AI tools. They do what you asked, but nobody asked them to lock the doors. If any of these sound familiar, your app needs a check before more people use it.
- You built it with Lovable, Bolt, v0, Cursor or Replit and it handles real user data
- Each new feature you add seems to break an old one
- You are not sure who can read your database
- It runs fine on your laptop but fails or slows down when it goes live
