Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
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.

How this class of weakness works · CWE-285

The application confirms who you are but does not properly check whether you are permitted to perform a given action, so authenticated users reach functions or data meant for others. Attackers test roles and object references to find the gap. Remediation is an authorization check on every request, evaluated against the acting user's actual permissions.

Recommended fix High confidence

Pathling Server 2.0.0

  1. 1. Back up your current Pathling Server configuration and any stored data
  2. 2. Review the Pathling Server 2.0.0 release notes for any breaking changes or migration requirements
  3. 3. Upgrade Pathling Server to version 2.0.0
  4. 4. Verify that the authorization model now correctly enforces per-resource read/write authorities in addition to operation authorities
  5. 5. Test that authenticated users can only access resources for which they have both the operation authority (e.g., pathling:search) and the matching per-resource authority (e.g., pathling:read:Patient)
Caveat Review 2.0.0 release notes for any breaking changes; major version upgrade may include API or configuration changes

No vendor fix exists The vendor has not published a patch for this.

There is no version to upgrade to and no patch to apply. Every affected install stays exposed until the vendor ships a fix — or somebody else builds one.
