By default `oak` does not allow transferring of hidden files with `Context.send` API. However, prior to version 17.1.3, this can be bypassed by encoding `/` as its URL encoded form `%2F`. For an attacker this has potential to read sensitive user data or to gain access to server secrets. Version 17.1.3 fixes the issue."

      "value": " `oak` es un framework de middleware para el servidor HTTP nativo de Deno, Deno Deploy, Node.js 16.5 y posteriores, Cloudflare Workers y Bun. De forma predeterminada, `oak` no permite la transferencia de archivos ocultos con la API `Context.send`. Sin embargo, antes de la versi\u00f3n 17.1.3, esto se puede omitir codificando `/` como su forma codificada de URL `%2F`. Para un atacante, esto tiene el potencial de leer datos confidenciales del usuario o de obtener acceso a secretos del servidor. La versi\u00f3n 17.1.3 soluciona el problema."
