In URI.js before version 1.19.4, the hostname can be spoofed by using a backslash (`\\`) character followed by an at (`@`) character. If the hostname is used in security decisions, the decision may be incorrect. Depending on library usage and attacker intent, impacts may include allow/block list bypasses, SSRF attacks, open redirects, or other undesired behavior. For example the URL `https://expected-example.com\\@observed-example.com` will incorrectly return `observed-example.com` if using an affected version. Patched versions correctly return `expected-example.com`. Patched versions match the behavior of other parsers which implement the WHATWG URL specification, including web browsers and Node's built-in URL class. Version 1.19.4 is patched against all known payload variants. Version 1.19.3 has a partial patch but is still vulnerable to a payload variant.]"}, {"lang": "es", "value": "URI.js es una biblioteca de mutaci\u00f3n de URL de JavaScript (paquete npm urijs). En URI.js versiones anteriores a 1.19.4, el nombre de host puede ser falsificado usando un car\u00e1cter barra invertida (\"\\\") seguido de un car\u00e1cter arroba (\"@\"). Si el nombre de host es usado en decisiones de seguridad, la decisi\u00f3n puede ser incorrecta. Dependiendo del uso de la biblioteca y la intenci\u00f3n del atacante, los impactos pueden incluir omisiones de lista de permisos y bloqueos, ataques SSRF, redireccionamientos abiertos u otros comportamientos no deseados. Por ejemplo, la URL \"https://expected-example.com\\@observed-example.com\" devolver\u00e1 incorrectamente \"observed-example.com\" si se usa una versi\u00f3n afectada. Las versiones parcheadas devuelven correctamente \"expected-example.com\". Las versiones parcheadas coinciden con el comportamiento de otros analizadores que implementan la especificaci\u00f3n de URL WHATWG, incluyendo los navegadores web y la clase URL incorporada de Node. La versi\u00f3n 1.19.4 est\u00e1 parcheada contra todas las variantes de carga \u00fatil conocidas.
