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.
