CVE-2026-47663
NVD analysis in progress
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.
What this means
- Exposure
- Exploitable remotely over the network, without authentication and with no action from the victim.
- Impact
- An attacker can read sensitive data.
- Weakness
- Authorisation is not checked in the right place, so a user acts outside their scope.
- Likelihood
- Its EPSS score stays low: nothing points to imminent exploitation, which is no reason to leave it unpatched.
What to doFold into the next patch cycle. Start with the instances exposed to the internet.
