      "value": "django CMS is a content management system powered by Django. Prior to 5.0.8 and in 5.1.0a1, the django CMS page cache in cms/cache/page.py ignores request headers declared by plugins through get_vary_cache_on(). The _page_cache_key function includes the cache prefix, site, language, path, and timezone but not the declared header values. Although set_page_cache adds those names to the response Vary header, get_page_cache retrieves the first stored variant under the same header-agnostic key. When CMS_PAGE_CACHE is enabled and a plugin varies content on a header such as Country-Code, one visitor can receive another visitor’s request-specific content, and an unauthenticated attacker can prime the cache with attacker-chosen content. This issue is fixed in versions 5.0.8 and 5.1.0."

      "value": "django CMS es un sistema de gestión de contenido impulsado por Django. Antes de la versión 5.0.8 y en la 5.1.0a1, la caché de página de django CMS en cms/cache/page.py ignora los encabezados de solicitud declarados por los plugins a través de get_vary_cache_on(). La función _page_cache_key incluye el prefijo de caché, el sitio, el idioma, la ruta y la zona horaria, pero no los valores de encabezado declarados. Aunque set_page_cache añade esos nombres al encabezado Vary de la respuesta, get_page_cache recupera la primera variante almacenada bajo la misma clave agnóstica de encabezado. Cuando CMS_PAGE_CACHE está habilitado y un plugin varía el contenido en un encabezado como Country-Code, un visitante puede recibir contenido específico de la solicitud de otro visitante, y un atacante no autenticado puede cebar la caché con contenido elegido por el atacante. Este problema se soluciona en las versiones 5.0.8 y 5.1.0."
