Vazamento de dados entre tenants (PoCs com EF Core e IA)

In this video, I practically explore the risk of cross-tenant leakage (data leakage between tenants) in multi-tenant applications, demonstrating two Proof of Concepts (PoCs) using different AI prompts and how superficiality can lead to the generation of insecure code in an ASP.NET Core API using EF Core. I explain how EF Core implements isolation mechanisms, such as global query filters and tenant-based context control. The focus is on showing that, depending on how the code is generated or structured, small decisions can open critical security vulnerabilities, reinforcing the importance of explicit validations, a well-defined architecture, and careful review when using AI in development.
