How to fix

Fixed in: September 2026 or later

Enable storage partition entitlement enforcement in SmileCDR HAPI FHIR configuration to restrict access between tenant partitions regardless of the bundle contents.

Technical details

The vulnerability allows an untrusted bundle body to override a partition identity established by a trusted source, and partition entitlement enforcement is not enabled by default. An authenticated attacker authorized for one tenant can craft a bundle request to access or modify another tenant's partition. The attack requires authentication but no additional user interaction beyond sending a malicious request.
