CVE-2024-55887

Severity8.6 High CVSS 3.1
Fixed in1.0.9
WeaknessXML external entity (XXE) (CWE-611)
Published13 Dec 2024
Updated17 Jun 2026

Description

Ucum-java is a FHIR Java library providing UCUM Services. In versions prior to 1.0.9, XML parsing performed by the UcumEssenceService is 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 ucum is being used to within a host where external clients can submit XML. Release 1.0.9 of Ucum-java fixes this vulnerability. As a workaround, ensure that the source xml for instantiating UcumEssenceService is trusted.
