Falta de verificação de autorização

O software permite que um usuário acesse recursos ou execute ações sem verificar se ele tem permissão para fazê-lo. É a brecha clássica onde o código autentifica (sabe quem é) mas não autoriza (valida se pode). Resultado: usuários comuns acessam dados sensíveis ou administrativos.

Example

Um sistema de e-commerce autentica o cliente, mas ao acessar /pedidos/123, não verifica se o pedido pertence àquele usuário — qualquer cliente logado vê qualquer pedido alheio. Ou um painel administrativo expõe endpoints que deleta contas, mas qualquer conta logada consegue chamar.

How to mitigate

Implemente verificação de autorização em todo endpoint ou ação sensível: valide não só identidade, mas permissões (roles, ACLs, policies). Use middleware ou decoradores (@RequireRole, @Authorize) e teste cenários onde usuários com privileégio baixo tentam acessar recursos alheios ou funções restritas.
