Lesson 6 – Practical 3 (Part 2) | Securing APIs with DTO & Preventing Mass Assignment in Spring Boot

In Lesson 6 – Practical 3 (Part 2), we fix the vulnerabilities demonstrated in Part 1 by properly securing our Spring Boot API using DTOs, validation, and explicit mapping. After exploiting mass assignment and privilege escalation, we now: ✅ Introduce DTOs to control request data ✅ Remove direct entity binding ✅ Implement explicit DTO → Entity mapping ✅ Apply input validation ✅ Enforce proper field restrictions ✅ Re-test previous attacks ✅ Verify that privilege escalation is blocked This lesson shows how small design changes can completely eliminate dangerous security flaws and improve long-term maintainability. You’ll learn how to build secure API boundaries that protect sensitive fields and prevent attackers from abusing automatic data binding. Ideal for Java developers, backend engineers, and anyone serious about building secure REST APIs. 👍 Like, comment, and subscribe if this helped you 💬 Questions and improvements are always welcome Follow me on my socials to connect and see more awesome stuff 📌 *GitHub:* [https://github.com/NganeEmmanue](https://github.com/NganeEmmanue) 💼 *LinkedIn:* [  / ngane-emmanuel-b25242150  ](  / ngane-emmanuel-b25242150  ) 📸 *Instagram:* @nganeemmanuel Github Repo: https://github.com/NganeEmmanuel/SFLL... 🏷️ Tags dto security fix,prevent mass assignment,spring boot secure api,java api hardening,secure rest api tutorial,backend security practical,privilege escalation prevention,spring boot validation,dto mapping java,secure coding practices,owasp api security,spring boot best practices,application security demo,secure backend development,api vulnerability fix,java security tutorial,rest api protection,data binding security,cybersecurity practical,java spring boot security
