      "value": "Nokogiri is an open source XML and HTML library for the Ruby programming language. Prior to 1.19.4, the NONET parse option, which Nokogiri turns on by default for Nokogiri::XML::Schema (see CVE-2020-26247), was not correctly enforced on the JRuby implementation. As a result, a schema parsed with default options could still cause external resources to be fetched over the network, potentially enabling SSRF or XXE attacks. This vulnerability is fixed in 1.19.4."

      "value": "Nokogiri es una biblioteca de código abierto de XML y HTML para el lenguaje de programación Ruby. Antes de la versión 1.19.4, la opción de análisis NONET, que Nokogiri activa por defecto para Nokogiri::XML::Schema (ver CVE-2020-26247), no se aplicaba correctamente en la implementación de JRuby. Como resultado, un esquema analizado con las opciones por defecto aún podía provocar que se obtuvieran recursos externos a través de la red, lo que potencialmente permitía ataques SSRF o XXE. Esta vulnerabilidad se corrigió en la versión 1.19.4."
