Exceção Não Capturada

Quando o código não trata adequadamente exceções ou erros gerados durante a execução, permitindo que eles se propaguem sem controle. Isso causa interrupção inesperada do programa, possível revelação de informações sensíveis em mensagens de erro e deixa a aplicação em estado indefinido ou vulnerável.

Ejemplo

Um endpoint web tenta acessar um arquivo ou banco de dados sem try-catch; se o recurso não existir, a exceção não tratada expõe stack traces contendo caminhos internos, credenciais ou detalhes da infraestrutura para o cliente atacante.

Cómo mitigar

Implemente blocos try-catch específicos para cada operação que possa falhar (I/O, banco de dados, rede). Defina um mecanismo centralizado de tratamento de erros que logue internamente sem expor detalhes ao usuário final, e sempre finalize recursos (conexões, arquivos) em blocos finally ou use try-with-resources.
