Descriptions

The CSSFontFaceSrcValue::fetch function in core/css/CSSFontFaceSrcValue.cpp in the Cascading Style Sheets (CSS) implementation in Blink, as used in Google Chrome before 46.0.2490.71, does not use the CORS cross-origin request algorithm when a font's URL appears to be a same-origin URL, which allows remote web servers to bypass the Same Origin Policy via a redirect.

La función CSSFontFaceSrcValue::fetch en core/css/CSSFontFaceSrcValue.cpp en la implementación Cascading Style Sheets (CSS) en Blink, como se utiliza en Google Chrome en versiones anteriores a 46.0.2490.71, no utiliza el algoritmo de petición de origen-cruzado CORS cuando la URL de una fuente parece ser una URL del mismo origen, lo que permite a servidores web remotos eludir la Same Origin Policy a través de un redireccionamiento.
