Prior to version 6.3.23, 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 impacts use cases where org.hl7.fhir.core is being used to within a host where external clients can submit XML. This issue has been patched in release 6.3.23. No known workarounds are available.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:N","score":8.6},"cwes":["CWE-611"],"references":["https://github.com/HL7/fhir-ig-publisher/releases/tag/1.6.22","https://github.com/HL7/fhir-ig-publisher/security/advisories/GHSA-59rq-22fm-x8q5","https://github.com/hapifhir/org.hl7.fhir.core/releases/tag/6.3.23","https://github.com/hapifhir/org.hl7.fhir.core/security/advisories/GHSA-6cr6-ph3p-f5rf"],"products":[],"source":"nvd","synced_at":"2026-10-19T21:54:38.012257375+00:00"},"epss":{"cve":"CVE-2024-45294","score":0.00975,"percentile":0.62109,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-6cr6-ph3p-f5rf","url":"https://osv.dev/vulnerability/GHSA-6cr6-ph3p-f5rf","summary":"XXE vulnerability in XSLT transforms in `org.hl7.fhir.core`","modified":"2026-02-04T03:35:09.337291Z","packages":[{"ecosystem":"Maven","name":"ca.uhn.hapi.fhir:org.hl7.fhir.dstu2016may","purl":"pkg:maven/ca.uhn.hapi.fhir/org.hl7.fhir.dstu2016may","ranges":["<6.3.23"],"fixed":["6.3.23"]},{"ecosystem":"Maven","name":"ca.uhn.hapi.fhir:org.hl7.fhir.dstu3","purl":"pkg:maven/ca.uhn.hapi.fhir/org.hl7.fhir.dstu3","ranges":["<6.3.23"],"fixed":["6.3.23"]},{"ecosystem":"Maven","name":"ca.uhn.hapi.fhir:org.hl7.fhir.r4","purl":"pkg:maven/ca.uhn.hapi.fhir/org.hl7.fhir.r4","ranges":["<6.3.23"],"fixed":["6.3.23"]},{"ecosystem":"Maven","name":"ca.uhn.hapi.fhir:org.hl7.fhir.r4b","purl":"pkg:maven/ca.uhn.hapi.fhir/org.hl7.fhir.r4b","ranges":["<6.3.23"],"fixed":["6.3.23"]},{"ecosystem":"Maven","name":"ca.uhn.hapi.fhir:org.hl7.fhir.r5","purl":"pkg:maven/ca.uhn.hapi.fhir/org.hl7.fhir.r5","ranges":["<6.3.23"],"fixed":["6.3.23"]},{"ecosystem":"Maven","name":"ca.uhn.hapi.fhir:org.hl7.fhir.utilities","purl":"pkg:maven/ca.uhn.hapi.fhir/org.hl7.fhir.utilities","ranges":["<6.3.23"],"fixed":["6.3.23"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
