Com 1.857 CVEs catalogadas e 189 classificadas como críticas, o histórico de vulnerabilidades da Mozilla reflete a complexidade de manter um navegador amplamente adotado. A taxa de exploração ativa — 9 entradas no CISA KEV, representando 0,48% do total — está em linha com a média geral do catálogo, o que indica um nível de exposição operacional compatível com o setor, sem desvio negativo expressivo. O tipo de falha mais recorrente é CWE-416 (use-after-free), uma classe de vulnerabilidade de memória com alto potencial de execução de código, e a CVE mais perigosa atualmente ativa, CVE-2016-9079, apresenta EPSS de 0,8792 — valor elevado que sugere probabilidade significativa de exploração continuada. Os 144 CVEs surgidos nos últimos 90 dias e a existência de 27 provas de conceito públicas reforçam a necessidade de monitoramento contínuo e priorização ágil de patches para ambientes que dependem de produtos Mozilla.
