Controle de acesso inadequado

A aplicação não valida corretamente quem pode acessar um recurso, função ou dado sensível. O atacante consegue contornar as verificações de autenticação ou autorização e executa ações não permitidas (ler dados de outro usuário, modificar configurações críticas, etc.). Essa é uma das falhas mais comuns e perigosas em desenvolvimento web e APIs.

Example

Uma API de banco de dados retorna dados do usuário ID 123 quando você requisita `/api/users/123`, mas não verifica se você é realmente o dono desse perfil ou um admin. Um atacante muda o ID na URL para `/api/users/456` e acessa dados de outro cliente sem nenhuma barreira.

How to mitigate

Sempre valide a identidade do usuário (autenticação) e depois confirme explicitamente se ele tem permissão para aquele recurso (autorização). Use tokens seguros, implemente controle de acesso baseado em papéis ou atributos, e teste cada endpoint com usuários diferentes para garantir que um não acessa dados do outro.
