@alanonai: Engineering for Vibe Coders: SQL Injection A lot of vibe-coded apps are vulnerable to something called SQL injection. Here is how it happens. You take user input and drop it directly into a database query. It works fine with normal input. But if someone sends input that includes SQL code, your database will execute it. That means instead of checking a password, it might return every user. Or bypass authentication completely. The scary part is how simple this is to prevent. You just use parameterized queries. That keeps your query structure fixed and treats user input as data, not code. No guessing. No escaping. Just safe by design. If your app builds SQL queries from user input, it is not just a bug. It is a security risk. Link in comments #ai #vibecoding #coding #programming #security
