# CVE-2026-113874: SmileCDR HAPI FHIR trusted tenant partition override

- Also known as: EUVD-2026-108274, GHSA-QW7X-RP32-35VW
- Severity: CVSS 8.1 (High), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N
- Known exploited (CISA KEV): no

## Summary

The vulnerability affects SmileCDR's HAPI FHIR healthcare data platform, which is used to manage multi-tenant clinical data. An attacker with access to one tenant could read or modify data belonging to another tenant's partition, because the platform lets untrusted request content override the trusted tenant identity and does not enforce partition access rules by default.

Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources.

## Affected

- SmileCDR HAPI FHIR: fixed in \*

## Description

SmileCDR HAPI FHIR allows an untrusted bundle body to replace a partition identity previously established by a trusted source, and does not enforce storage partition entitlement by default. An attacker authorized for one tenant can read from or write to another tenant's partition.
