Title
Pathling: Typed CRUD/search/batch providers can lead to server-wide PHI exfiltration and cross-resource mutation
Summary
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.

Antes de la versi\u00f3n 2.0.0 de Pathling Server, la superficie FHIR tipada de CRUD/b\u00fasqueda/lote de Pathling permite a un llamador autenticado con solo autoridades de operaci\u00f3n gruesas actuar sobre familias de recursos elegidas por el atacante porque esos puntos de entrada no aplican consistentemente las autoridades documentadas por recurso de \u2019lectura\u2019 y \u2019escritura\u2019. El modelo de autorizaci\u00f3n documentado requiere que una autoridad de operaci\u00f3n (p. ej. \u2019pathling:search\u2019) se empareje con la autoridad de \u2019lectura\u2019 o \u2019escritura\u2019 por recurso correspondiente (p. ej. \u2019pathling:read:Patient\u2019). Eliminar y lote est\u00e1n documentados para requerir autoridad de escritura para todos los tipos de recursos referenciados. Sin embargo, la b\u00fasqueda tipada, la actualizaci\u00f3n y los manejadores relacionados est\u00e1n anotados solo con \u2019@OperationAccess(...)\u2019 y act\u00faan sobre el tipo de recurso seleccionado por el proveedor sin verificar la autoridad por recurso correspondiente.

Experimental. This forecast is provided for visualization only and may change without notice. Do not use it for operational decisions.
Forecast uses a logistic model when the trend is rising, or an exponential decay model when the trend is falling. Fitted via linearized least squares.

Nomenclature
- Seen: The vulnerability was mentioned, discussed, or observed by the user.
- Confirmed: The vulnerability has been validated from an analyst's perspective.
- Published Proof of Concept: A public proof of concept is available for this vulnerability.
- Exploited: The vulnerability was observed as exploited by the user who reported the sighting.
- Patched: The vulnerability was observed as successfully patched by the user who reported the sighting.
- Not exploited: The vulnerability was not observed as exploited by the user who reported the sighting.
- Not confirmed: The user expressed doubt about the validity of the vulnerability.
- Not patched: The vulnerability was not observed as successfully patched by the user who reported the sighting.
Vulnerability timeline
Sightings and recorded dates, grouped by day · UTC
How durations are calculated
Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.
Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.
