AI is now smart enough to reconstruct your database from what looks like harmless errors:
- SQL errors (constraint violations, duplicate entries)
- ORM/Model exceptions (table names, class names, line numbers)
- NoSQL hints (like MongoDB’s “document not found” or “index violation”)
Why is this dangerous?
Attackers can gradually infer your schema:
- SQL → table names, keys, relationships
- NoSQL → collection names, document structures, indexes
Insight
Not all databases leak the same way:
- Relational DBs often reveal too much detail.
- NoSQL may leak less by default, but verbose logging or misconfiguration changes the game.
What can you do?
- Never expose raw errors in production.
- Use generic error handling.
- Regularly audit your API responses.
What about you?
- Have you ever seen a “simple” DB error reveal way too much?
- If you had to choose: SQL with verbose errors or NoSQL with misconfig risks — which one feels safer to you, and why?
