CVE-2026-47663 Details
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.
A vulnerability in Pathling Server's typed CRUD, search, and batch FHIR operations prior to version 2.0.0 allows authenticated users with limited operation authorities to manipulate selected resource families. This issue arises because the entry points fail to consistently apply the required per-resource read and write authorities, enabling potential cross-resource privacy data exfiltration and unauthorized modifications. The vulnerability is particularly concerning for delete and batch operations, which can exacerbate the impact by affecting multiple resource families simultaneously.
Users are advised to update to Pathling Server version 2.0.0 or later, and to ensure that the per-resource read or write authority is enforced on all typed CRUD, search, and batch entry points. Instructions for updating can be found in the Pathling GitHub repository.
