Developers: the 3 security bugs I find most often in code reviews: 1. IDOR: /api/orders/{id} doesn't check the order belongs to the logged-in user 2. Secrets in logs (tokens, OTPs, full card numbers) 3. Mass assignment: binding request JSON straight into the entity, so users can set isAdmin=true All three are easy to fix and easy to miss.
