CVE-2026-47663: Pathling: Typed CRUD/search/batch providers can lead to server-wide PHI exfiltration and cross-resource mutation

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.
