CVE-2026-47662: Aehrc Pathling

High severity, CVSS 8.7. EPSS: 0.4% chance of exploitation in the next 30 days.

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.
