This flaw has not been addressed in the maintained version of the library and has no current mitigation other than to disable DTD processing. This can be accomplished via the DOM using a standard parser feature, or via SAX using the XERCES_DISABLE_DTD environment variable.","published":"2019-12-18T20:15:15.000Z","lastModified":"2026-06-17T01:50:59.000Z","status":"Modified","sourceIdentifier":"security@apache.org","cvss":{"version":"3.1","score":8.1,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H"},"cwe":["CWE-416"],"affected":["apache/xerces-c\\+\\+","redhat/enterprise linux desktop","redhat/enterprise linux eus","redhat/enterprise linux server","redhat/enterprise linux server aus","redhat/enterprise linux server tus","redhat/enterprise linux workstation","debian/debian linux","oracle/goldengate","fedoraproject/fedora"],"epss":{"score":0.09503,"percentile":0.95419,"date":"2026-10-27","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (9.50%).
