      "value": "Pathling is a set of tools that make it easier to use FHIR and clinical terminology within health data analytics. Prior to version 2.0.0 of Pathling Server, Pathling's typed CRUD/search/batch FHIR surface allows an authenticated caller with only coarse operation authorities to act on attacker-chosen resource families because those entrypoints do not consistently enforce the documented per-resource `read` and `write` authorities. The documented authorization model requires an operation authority (e.g. `pathling:search`) to be paired with the matching per-resource `read` or `write` authority (e.g. `pathling:read:Patient`). Delete and batch are documented to require write authority for all referenced resource types. However, typed search, update, and related handlers are annotated only with `@OperationAccess(...)` and act on the provider-selected resource type without checking the corresponding per-resource authority. This is fixed in Pathling Server 2.0.0."

      "value": "Pathling es un conjunto de herramientas que facilitan el uso de FHIR y la terminología clínica dentro del análisis de datos de salud. Antes de la versión 2.0.0 de Pathling Server, la superficie FHIR tipada de CRUD/búsqueda/lote de Pathling permite a un llamador autenticado con solo autoridades de operación generales actuar sobre familias de recursos elegidas por el atacante porque esos puntos de entrada no aplican consistentemente las autoridades documentadas de ’lectura’ y ’escritura’ por recurso. El modelo de autorización documentado requiere que una autoridad de operación (p. ej., ’pathling:search’) se empareje con la autoridad de ’lectura’ o ’escritura’ por recurso correspondiente (p. ej., ’pathling:read:Patient’). Eliminar y lote están documentados para requerir autoridad de escritura para todos los tipos de recursos referenciados. Sin embargo, la búsqueda tipada, la actualización y los manejadores relacionados están anotados solo con ’@OperationAccess(...)’ y actúan sobre el tipo de recurso seleccionado por el proveedor sin verificar la autoridad por recurso correspondiente. Esto se ha corregido en Pathling Server 2.0.0."
