Vexday analysis

Com 57 CVEs catalogadas e nenhuma registrada no CISA KEV, o histórico de vulnerabilidades da Cloudflare apresenta taxa de exploração ativa abaixo da média geral do catálogo, o que indica um perfil de risco operacional relativamente contido. O tipo de falha mais frequente é CWE-20 (validação inadequada de entrada), categoria que exige atenção contínua em componentes expostos a dados externos. A CVE mais perigosa no momento, CVE-2021-3907, possui EPSS de 0,04, sugerindo probabilidade de exploração ainda baixa, embora seja o ponto focal para priorização de correção. A ausência de PoCs públicas reforça o cenário atual de menor pressão imediata, mas as duas CVEs de severidade crítica devem ser monitoradas de perto dado seu potencial de impacto.
