Descriptions
Under certain circumstances the "fetch()" API can return transient local copies of resources that were sent with a "no-store" or "no-cache" cache header instead of downloading a copy from the network as it should. This can result in previously stored, locally cached data of a website being accessible to users if they share a common profile while browsing. This vulnerability affects Firefox ESR < 52.7 and Firefox < 59.
Bajo ciertas circunstancias, la API "fetch()" puede devolver copias locales transitorias de recursos que se enviaron con una cabecera de caché "no-store" o "no-cache" en lugar de descargar una copia de la red, que es lo recomendado. Esto puede dar lugar a que los usuarios puedan acceder a los datos almacenados previamente y almacenados en la caché local de un sitio web si comparten un perfil común durante la navegación. Esta vulnerabilidad afecta a las versiones anteriores a la 52.7 de Firefox ESR y las versiones anteriores a la 59 de Firefox.
