Asserção acessível por entrada não confiável

Código de produção contém asserções (assert statements) que podem ser disparadas por dados fornecidos pelo usuário ou atacante, causando falha abrupta da aplicação. Diferente de validação, asserções são mecanismos de debug que não deveriam controlar o fluxo normal — quando acionadas, encerram o programa, provocando negação de serviço.

Ejemplo

Um servidor web recebe um parâmetro `user_id` e executa `assert user_id > 0` antes de consultar o banco. Um atacante envia `user_id=0` ou negativo, a asserção falha e derruba o servidor. O código assume que validação já ocorreu, mas ela não existe.

Cómo mitigar

Substitua asserções por validação explícita com tratamento de erro apropriado (throw exception, retornar código de erro). Remova ou desative asserções em builds de produção. Use asserções apenas para condições internas que nunca deveriam ocorrer, nunca para entrada de usuário.
