O portfólio da Apache Software Foundation acumula 1.872 CVEs catalogadas, das quais 215 são de severidade crítica e 83 contam com prova de conceito pública — fatores que ampliam a superfície de risco operacional para equipes de segurança. A taxa de exploração ativa é especialmente preocupante: 28 vulnerabilidades constam no catálogo KEV da CISA, representando uma proporção 3,3 vezes acima da média geral do catálogo, o que indica atenção consistente de agentes maliciosos ao ecossistema Apache. A falha mais comum é CWE-20 (validação inadequada de entrada), padrão estrutural que tende a se manifestar em múltiplos produtos e versões, exigindo revisão ampla e não pontual. Destaque para CVE-2021-40438, a vulnerabilidade de maior risco ativo no momento, com EPSS máximo de 1,0 — probabilidade de exploração na prática praticamente certa —, o que a torna prioridade imediata de remediação para qualquer organização que opere componentes Apache afetados.
