O tipo de falha mais recorrente é CWE-200 (exposição indevida de informações), indicando um padrão histórico de problemas relacionados ao controle de acesso a dados. A CVE mais perigosa no momento, CVE-2024-53991, registra EPSS de aproximadamente 0,25, valor que merece atenção dado que reflete probabilidade não trivial de exploração nos próximos 30 dias.
