Este feed é automaticamente atualizado, mas com um pequeno atraso perceptível (minutos a horas), desde o momento em que um CVE é anunciado até o momento em que é acessível neste feed.

A fonte deste feed é um conjunto de issues do GitHub, filtrado pelo rótulo controlado e restrito official-cve-feed. Os dados brutos são armazenados em um Google Cloud Bucket que é somente escrito por um pequeno número de membros confiáveis da Comunidade.
