This vulnerability only impacts Discourse instances configured to use `FileStore::LocalStore` which means uploads and backups are stored locally on disk. If an attacker knows the name of the Discourse backup file, the attacker can trick nginx into sending the Discourse backup file with a well crafted request. This issue is patched in the latest stable, beta and tests-passed versions of Discourse. Users are advised to upgrade. Users unable to upgrade can either 1. Download all local backups on to another storage device, disable the `enable_backups` site setting and delete all backups until the site has been upgraded to pull in the fix. Or 2. Change the `backup_location` site setting to `s3` so that backups are stored and downloaded directly from S3."}, {"lang": "es", "value": "Discourse es una plataforma de c\u00f3digo abierto para debates comunitarios. Esta vulnerabilidad solo afecta a las instancias de Discourse configuradas para usar `FileStore::LocalStore`, lo que significa que las cargas y las copias de seguridad se almacenan localmente en el disco. Si un atacante conoce el nombre del archivo de copia de seguridad de Discourse, puede enga\u00f1ar a nginx para que env\u00ede el archivo de copia de seguridad de Discourse con una solicitud bien manipulada. Este problema est\u00e1 parcheado en las \u00faltimas versiones estables, beta y de pruebas aprobadas de Discourse. Se recomienda a los usuarios que actualicen. Los usuarios que no puedan actualizar pueden 1. Descargar todas las copias de seguridad locales en otro dispositivo de almacenamiento, deshabilitar la configuraci\u00f3n del sitio `enable_backups` y eliminar todas las copias de seguridad hasta que el sitio se haya actualizado para incorporar la soluci\u00f3n.
