      "value": "Directus is a real-time API and App dashboard for managing SQL database content. Prior to 11.17.0, Directus' GraphQL endpoints (/graphql and /graphql/system) did not deduplicate resolver invocations within a single request. An authenticated user could exploit GraphQL aliasing to repeat an expensive relational query many times in a single request, forcing the server to execute a large number of independent complex database queries concurrently, multiplying database load linearly with the number of aliases. The existing token limit on GraphQL queries still permitted enough aliases for significant resource exhaustion, while the relational depth limit applied per alias without reducing the total number executed. Rate limiting is disabled by default, meaning no built-in throttle prevented this from causing CPU, memory, and I/O exhaustion that could degrade or crash the service. Any authenticated user, including those with minimal read-only permissions, could trigger this condition. This vulnerability is fixed in 11.17.0."

      "value": "Directus es un panel de control de API y aplicación en tiempo real para gestionar contenido de base de datos SQL. Antes de la versión 11.17.0, los endpoints GraphQL de Directus (/graphql y /graphql/system) no deduplicaban las invocaciones del resolvedor dentro de una única solicitud. Un usuario autenticado podría explotar el aliasing de GraphQL para repetir una consulta relacional costosa muchas veces en una única solicitud, forzando al servidor a ejecutar un gran número de consultas de base de datos complejas e independientes de forma concurrente, multiplicando la carga de la base de datos linealmente con el número de alias. El límite de tokens existente en las consultas GraphQL aún permitía suficientes alias para un agotamiento significativo de recursos, mientras que el límite de profundidad relacional se aplicaba por alias sin reducir el número total ejecutado. La limitación de velocidad está deshabilitada por defecto, lo que significa que ningún mecanismo de limitación incorporado impidió que esto causara agotamiento de CPU, memoria y E/S que podría degradar o bloquear el servicio. Cualquier usuario autenticado, incluidos aquellos con permisos mínimos de solo lectura, podría desencadenar esta condición. Esta vulnerabilidad está corregida en la versión 11.17.0."
