Consumo descontrolado de recursos (esgotamento)

A aplicação não limita adequadamente o consumo de recursos (memória, CPU, conexões, disco) em resposta a requisições do usuário ou eventos externos. Um atacante explora isso enviando muitas requisições ou dados grandes para derrubar o serviço, indisponibilizando-o para usuários legítimos.

Ejemplo

Um endpoint de upload aceita arquivos sem limitar o tamanho ou taxa de envio; um atacante manda gigabytes contínuos até a aplicação ficar sem espaço em disco ou memória. Ou um loop sem condição de parada processa dados de entrada indefinidamente, travando a CPU.

Cómo mitigar

Implemente limites explícitos: tamanho máximo de arquivo/requisição, rate limiting (requisições por IP/usuário), timeouts, pool de conexões com tamanho fixo, e monitoramento de recursos. Valide e rejeite early entradas que excedem esses limites.
