Lesson 6 – DTOs & Mass Assignment Attacks | Prevent Privilege Escalation in Spring Boot APIs

Описание: In Lesson 6 of our API Security series, we explore how improper data binding can lead to mass assignment attacks and privilege escalation in Spring Boot applications.

Many modern API breaches happen when developers bind request data directly to database entities. This lesson explains why that shortcut is dangerous and how DTOs (Data Transfer Objects) create secure boundaries.

In this video, you’ll learn how to:

✅ Understand what DTOs are and why they exist
✅ See how direct entity binding creates vulnerabilities
✅ Learn how mass assignment attacks work
✅ Understand privilege escalation in APIs
✅ Protect endpoints using DTOs and explicit mapping
✅ Design safer, maintainable API contracts

This lesson prepares you for the next practical demo, where we will exploit and then secure an API using proper DTO patterns.

Ideal for Java developers, backend engineers, and security-focused API designers.
