CVE-2024-45294: XXE vulnerability in XSLT transforms in `org.hl7.fhir.core`

September 6, 2024

XSLT transforms performed by various components are vulnerable to XML external entity injections. A processed XML file with a malicious DTD tag ( <!DOCTYPE foo [<!ENTITY example SYSTEM "/etc/passwd"> ]> could produce XML containing data from the host system. This impacts use cases where org.hl7.fhir.core is being used to within a host where external clients can submit XML.
