Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
The org.hl7.fhir.publisher.cli and org.hl7.fhir.publisher.core packages are vulnerable before version 1.7.4. XSLT transforms in these components are open to XML external entity injection, so a crafted XML file can cause the processor to disclose data from the host system. The risk applies where external clients can submit XML to a host running the publisher. Upgrade to version 1.7.4, which contains the fix; no workaround is listed.
