CVE-2026-47663

Full vulnerability record from the local CVENow database.

Description

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 gruesas actuar sobre familias de recursos elegidas por el atacante porque esos puntos de entrada no aplican consistentemente las autoridades documentadas por recurso de ’lectura’ y ’escritura’. 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 corrige en Pathling Server 2.0.0."
