Análise Vexday

O ecossistema Nextcloud acumula 266 CVEs catalogadas, com volume de novas vulnerabilidades ainda ativo — 27 surgiram nos últimos 90 dias —, mas apresenta taxa de exploração ativa abaixo da média geral do catálogo, sem registros no CISA KEV. O tipo de falha predominante é CWE-284 (controle de acesso inadequado), o que indica fragilidades estruturais na gestão de permissões que tendem a ampliar a superfície de ataque em ambientes colaborativos. A CVE mais relevante no momento é CVE-2022-24838, com escore EPSS de 0,3155 — o mais alto observado no conjunto —, sinalizando probabilidade não negligenciável de exploração e merecendo atenção prioritária em qualquer plano de remediação. A existência de 2 CVEs com PoC pública, combinada a 4 falhas críticas, reforça a necessidade de monitoramento contínuo mesmo em um cenário onde a exploração confirmada ainda é ausente.
