      "value": "Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. The MongoDB `explain()` method provides detailed information about query execution plans, including index usage, collection scanning behavior, and performance metrics. Prior to version 8.5.0-alpha.5, Parse Server permits any client to execute explain queries without requiring the master key. This exposes database schema structure and field names, index configurations and query optimization details, query execution statistics and performance metrics, and potential attack vectors for database performance exploitation. In version 8.5.0-alpha.5, a new `databaseOptions.allowPublicExplain` configuration option has been introduced that allows to restrict `explain` queries to the master key. The option defaults to `true` for now to avoid a breaking change in production systems that depends on public `explain` availability. In addition, a security warning is logged when the option is not explicitly set, or set to `true`. In a future major release of Parse Server, the default will change to `false`. As a workaround, implement middleware to block explain queries from non-master-key requests, or monitor and alert on explain query usage in production environments."

      "value": "Parse Server es un backend de c\u00f3digo abierto que puede implementarse en cualquier infraestructura que pueda ejecutar Node.js. El m\u00e9todo \u0027explain()\u0027 de MongoDB proporciona informaci\u00f3n detallada sobre los planes de ejecuci\u00f3n de consultas, incluyendo el uso de \u00edndices, el comportamiento de escaneo de colecciones y las m\u00e9tricas de rendimiento. Antes de la versi\u00f3n 8.5.0-alpha.5, Parse Server permite a cualquier cliente ejecutar consultas explain sin requerir la clave maestra. Esto expone la estructura del esquema de la base de datos y los nombres de los campos, las configuraciones de \u00edndices y los detalles de optimizaci\u00f3n de consultas, las estad\u00edsticas de ejecuci\u00f3n de consultas y las m\u00e9tricas de rendimiento, y posibles vectores de ataque para la explotaci\u00f3n del rendimiento de la base de datos. En la versi\u00f3n 8.5.0-alpha.5, se ha introducido una nueva opci\u00f3n de configuraci\u00f3n \u0027databaseOptions.allowPublicExplain\u0027 que permite restringir las consultas \u0027explain\u0027 a la clave maestra. La opci\u00f3n por defecto es \u0027true\u0027 por ahora para evitar un cambio disruptivo en los sistemas de producci\u00f3n que dependen de la disponibilidad p\u00fablica de \u0027explain\u0027. Adem\u00e1s, se registra una advertencia de seguridad cuando la opci\u00f3n no se establece expl\u00edcitamente, o se establece en \u0027true\u0027. En una futura versi\u00f3n principal de Parse Server, el valor por defecto cambiar\u00e1 a \u0027false\u0027. Como soluci\u00f3n alternativa, implemente middleware para bloquear las consultas explain de solicitudes sin clave maestra, o monitoree y alerte sobre el uso de consultas explain en entornos de producci\u00f3n."
