Recommended response

  1. 1Check inventory. Check lockfiles and deployed manifests for hapifhir/ca.uhn.hapi.fhir:org.hl7.fhir.validation, hapifhir/ca.uhn.hapi.fhir:org.hl7.fhir.validation.cli, hapifhir/org.hl7.fhir.core.
  2. 2Review the reported fix. Update hapifhir/ca.uhn.hapi.fhir:org.hl7.fhir.validation to 6.9.11; hapifhir/ca.uhn.hapi.fhir:org.hl7.fhir.validation.cli to 6.9.11; hapifhir/org.hl7.fhir.core to 6.9.11 if you use the affected versions. Test the change in a non-production environment first.

Upstream source description

HAPI FHIR is a complete implementation of the HL7 FHIR standard for healthcare interoperability in Java. Prior to 6.9.11, the hidden scan command concatenates attacker-controlled Implementation Guide titles, profile titles, and source references into scan.html without escaping in Scanner.java. As a result, a user who scans an attacker-supplied IG/profile and then opens or publishes the generated local/CI HTML report can trigger stored cross-site scripting, executing attacker-controlled JavaScript in the report's browser context. This issue is fixed in version 6.9.11.
