{"id":"CVE-2024-55887","aliases":["GHSA-w9j7-phm3-f97j"],"url":"https://o3.security/vulnerability/CVE-2024-55887","summary":"Ucum-java has an XXE vulnerability in XML parsing","details":"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.","published":"2024-12-13T16:08:55.658Z","modified":"2026-07-15T01:49:13.643158795Z","cvss":{"score":8.6,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Maven","name":"org.fhir:ucum","fixedVersion":"1.0.9"}],"fix":null,"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/55xxx/CVE-2024-55887.json"},{"type":"ADVISORY","url":"https://github.com/FHIR/Ucum-java/security/advisories/GHSA-w9j7-phm3-f97j"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-55887"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-15T01:49:13.643158795Z"}}
