XXE vulnerability in XSLT transforms in `org.hl7.fhir.core`
Impact
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.
Patches
This issue has been patched in release 6.3.23
Workarounds
None.
