A flaw was found in HAPI FHIR - HL7 FHIR Core Artifacts. eXtensible Stylesheet Language Transformations (XSLT) transforms performed by various components are vulnerable to XML external entity injections. A processed XML file with a malicious DTD tag could produce XML containing data from the host system. This issue impacts use cases where org.hl7.fhir.core is being used within a host where external clients can submit XML.
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
