      "value": "In OpenStack Cyborg before 16.0.1, the Accelerator Request (ARQ) API does not enforce project ownership at any layer. The project_id column in the database is never populated (NULL for every ARQ), database queries have no project filtering, and policy checks are self-referential (the authorize_wsgi decorator compares the caller's project_id with itself rather than the target resource). Any authenticated non-admin user can complete various actions such as deleting ARQs bound to other projects' instances, aka cross-tenant denial of service."

      "value": "En OpenStack Cyborg antes de 16.0.1, la API de Solicitud de Acelerador (ARQ) no aplica la propiedad del proyecto en ninguna capa. La columna project_id en la base de datos nunca se rellena (NULL para cada ARQ), las consultas a la base de datos no tienen filtrado por proyecto, y las comprobaciones de políticas son autorreferenciales (el decorador authorize_wsgi compara el project_id del llamador consigo mismo en lugar de con el recurso objetivo). Cualquier usuario autenticado no administrador puede completar varias acciones, como eliminar ARQs vinculadas a instancias de otros proyectos, también conocido como denegación de servicio entre inquilinos."
