Descriptions

Node.js: All versions prior to Node.js 6.15.0, 8.14.0, 10.14.0 and 11.3.0: Hostname spoofing in URL parser for javascript protocol: If a Node.js application is using url.parse() to determine the URL hostname, that hostname can be spoofed by using a mixed case "javascript:" (e.g. "javAscript:") protocol (other protocols are not affected). If security decisions are made about the URL based on the hostname, they may be incorrect.

Node.js: Todas las versiones anteriores a la 6.15.0, 8.14.0, 10.14.0 y 11.3.0: Suplantación dek nombre del host en un analizador de URL para el protocolo JavaScript. Si una aplicación de Node.js está empleando url.parse() para determinar el nombre de host de la URL, dicho nombre puede suplantarse mediante un protocolo "javascript:" de letra mixta (por ejemplo, "javAscript:"). Otros protocolos no se han visto afectados. Si se realizan decisiones de seguridad sobre la URL basadas en su nombre de host, podrían ser incorrectas.
