Descriptions

Node.js versions before 10.23.1, 12.20.1, 14.15.4, 15.5.1 allow two copies of a header field in an HTTP request (for example, two Transfer-Encoding header fields). In this case, Node.js identifies the first header field and ignores the second. This can lead to HTTP Request Smuggling.

Node.js versiones anteriores a 10.23.1, 12.20.1, 14.15.4, 15.5.1 permiten dos copias de un campo de encabezado en una petición HTTP (por ejemplo, dos campos de encabezado Transfer-Encoding). En este caso, Node.js identifica el primer campo de encabezado e ignora el segundo. Esto puede conllevar a un Tráfico no Autorizado de Peticiones HTTP

A flaw was found in nodejs. Affected versions of Node.js allow two copies of a header field in an HTTP request. The first header field is recognized while the second is ignored leading to HTTP request smuggling. The highest threat from this vulnerability is to data confidentiality and integrity.
