Windows Server acumula 831 CVEs catalogadas, das quais 33 estão confirmadas em exploração ativa no catálogo KEV da CISA — uma taxa 8,8 vezes acima da média geral do catálogo, o que indica exposição operacional significativamente elevada. A CVE mais perigosa em atividade, CVE-2019-0708, registra EPSS de 1,0, sinalizando probabilidade máxima de exploração e exigindo atenção prioritária em ambientes que ainda não aplicaram a correção correspondente. O tipo de falha mais recorrente é CWE-59 (improper link resolution before file access, ou "link following"), sugerindo que controles de integridade de sistema de arquivos e privilégios de acesso devem compor a linha de defesa prioritária. Embora nenhuma CVE nova tenha surgido nos últimos 90 dias, o perfil histórico da plataforma — com 3 falhas críticas ativas e EPSS máximo observado de 0,99999 — reforça a necessidade de gestão contínua e rigorosa de patches.
