• CVE-2024-52007: 0.90% estimated exploitation activity in the next 30 days; percentile 59.67 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

Summary XSLT parsing 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.

# Patch Next advisory brief: CVE-2024-52007

Advisory: XXE vulnerability in XSLT parsing in `org.hl7.fhir.core`
IDs: CVE-2024-52007, GHSA-gr3c-q7xf-47vh
Record: https://patchnext.com/advisories/cve-2024-52007 (revision 1, source checked 26 Oct 2026, 16:31 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 7.7)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: ca.uhn.hapi.fhir:org.hl7.fhir.dstu2016may 6.4.0; ca.uhn.hapi.fhir:org.hl7.fhir.dstu3 6.4.0; ca.uhn.hapi.fhir:org.hl7.fhir.r4b 6.4.0; ca.uhn.hapi.fhir:org.hl7.fhir.utilities 6.4.0; ca.uhn.hapi.fhir:org.hl7.fhir.r4 6.4.0; ca.uhn.hapi.fhir:org.hl7.fhir.r5 6.4.0. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven ca.uhn.hapi.fhir:org.hl7.fhir.dstu2016may: affected < 6.4.0; fixed in 6.4.0
- Maven ca.uhn.hapi.fhir:org.hl7.fhir.dstu3: affected < 6.4.0; fixed in 6.4.0
- Maven ca.uhn.hapi.fhir:org.hl7.fhir.r4b: affected < 6.4.0; fixed in 6.4.0
- Maven ca.uhn.hapi.fhir:org.hl7.fhir.utilities: affected < 6.4.0; fixed in 6.4.0
- Maven ca.uhn.hapi.fhir:org.hl7.fhir.r4: affected < 6.4.0; fixed in 6.4.0
- Maven ca.uhn.hapi.fhir:org.hl7.fhir.r5: affected < 6.4.0; fixed in 6.4.0

## Suggested inspection (read-only)
- Maven ca.uhn.hapi.fhir:org.hl7.fhir.dstu2016may: check the installed version with your package manager.
- Maven ca.uhn.hapi.fhir:org.hl7.fhir.dstu3: check the installed version with your package manager.
- Maven ca.uhn.hapi.fhir:org.hl7.fhir.r4b: check the installed version with your package manager.
- Maven ca.uhn.hapi.fhir:org.hl7.fhir.utilities: check the installed version with your package manager.
- Maven ca.uhn.hapi.fhir:org.hl7.fhir.r4: check the installed version with your package manager.
- Maven ca.uhn.hapi.fhir:org.hl7.fhir.r5: check the installed version with your package manager.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on ca.uhn.hapi.fhir:org.hl7.fhir.dstu2016may, ca.uhn.hapi.fhir:org.hl7.fhir.dstu3, ca.uhn.hapi.fhir:org.hl7.fhir.r4b, ca.uhn.hapi.fhir:org.hl7.fhir.utilities, ca.uhn.hapi.fhir:org.hl7.fhir.r4, ca.uhn.hapi.fhir:org.hl7.fhir.r5.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.
