CVE-2026-47664

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, the $import-pnp operation in Pathling Server accepts a caller-supplied exportUrl and uses it as the remote FHIR Bulk Export endpoint without constraining it to a trusted source. When PNP credentials are configured, Pathling builds a credentialed bulk-export client targeting the caller-chosen host, downloads manifest-selected files, and then reclassifies those staged files as trusted local file:// imports - bypassing the configured allowableSources allowlist that protects the ordinary $import operation. This is fixed in Pathling Server 2.0.0. As a workaround, disable the $import-pnp operation (pathling.operations.importPnpEnabled=false) or do not configure PNP credentials.
