  • Disclosed: 06.09.2024
  • Updated: 11.10.2026 12:22

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.
