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.","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/FHIR/Ucum-java/security/advisories/GHSA-w9j7-phm3-f97j"],"products":[],"source":"nvd","synced_at":"2026-10-19T21:57:36.180738747+00:00"},"epss":{"cve":"CVE-2024-55887","score":0.00557,"percentile":0.46485,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-w9j7-phm3-f97j","url":"https://osv.dev/vulnerability/GHSA-w9j7-phm3-f97j","summary":"Ucum-java has an XXE vulnerability in XML parsing","modified":"2024-12-13T21:12:11.218160Z","packages":[{"ecosystem":"Maven","name":"org.fhir:ucum","purl":"pkg:maven/org.fhir/ucum","ranges":["<1.0.9"],"fixed":["1.0.9"]}]}],"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).
