In this course, we will examine three very relevant security risks that were merged into larger topics in the OWASP Top Ten 2021 list. It’s still important to know the details of how these risks work. We will explore XML External Entities (XXE), Cross-Site Scripting (XSS) and Insecure Deserialization.
