{"id":"RHLW-2026-f43b17f69a51feee","summary":"Lightwell Security Advisory: dom4j 1.6.1.rhlw-00004","details":"Red Hat Lightwell has released dom4j:dom4j 1.6.1.rhlw-00004 with backported fixes for CVE-2018-1000632 and CVE-2020-10683.\n\nCVE-2018-1000632: dom4j version prior to version 2.1.1 contains a CWE-91: XML Injection vulnerability in Class: Element. Methods: addElement, addAttribute that can result in an attacker tampering with XML documents through XML injection. This attack appear to be exploitable via an attacker specifying attributes or elements in the XML document. This vulnerability appears to have been fixed in 2.1.1 or later.\n\nCVE-2020-10683: dom4j before 2.0.3 and 2.1.x before 2.1.3 allows external DTDs and External Entities by default, which might enable XXE attacks. However, there is popular external documentation from OWASP showing how to enable the safe, non-default behavior in any application that uses dom4j.\n\nThis patched artifact is a drop-in replacement for dom4j:dom4j 1.6.1 from Maven Central.","modified":"2026-10-27T08:45:04.753953859Z","published":"2026-10-22T16:49:52Z","upstream":["CVE-2018-1000632","CVE-2020-10683","GHSA-6pcc-3rfx-4gpm","GHSA-hwj3-m3p6-hj38"],"references":[{"type":"WEB","url":"https://lists.apache.org/thread.html/00571f362a7a2470fba50a31282c65637c40d2e21ebe6ee535a4ed74%40%3Ccommits.maven.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/4a77652531d62299a30815cf5f233af183425db8e3c9a824a814e768%40%3Cdev.maven.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/5a020ecaa3c701f408f612f7ba2ee37a021644c4a39da2079ed3ddbc%40%3Ccommits.maven.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/708d94141126eac03011144a971a6411fcac16d9c248d1d535a39451%40%3Csolr-user.lucene.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/7e9e78f0e4288fac6591992836d2a80d4df19161e54bd71ab4b8e458%40%3Cdev.maven.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/7f6e120e6ed473f4e00dde4c398fc6698eb383bd7857d20513e989ce%40%3Cdev.maven.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/9d4c1af6f702c3d6d6f229de57112ddccac8ce44446a01b7937ab9e0%40%3Ccommits.maven.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/d7d960b2778e35ec9b4d40c8efd468c7ce7163bcf6489b633491c89f%40%3Cdev.maven.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/rb1b990d7920ae0d50da5109b73b92bab736d46c9788dd4b135cb1a51%40%3Cnotifications.freemarker.apache.org%3E"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:0362"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:0364"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:0365"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:0380"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:1159"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:1160"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:1161"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:1162"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:3172"},{"type":"REPORT","url":"https://github.com/dom4j/dom4j/issues/48"},{"type":"FIX","url":"https://github.com/dom4j/dom4j/commit/e598eb43d418744c4dbf62f647dd2381c9ce9387"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2018-1000632"},{"type":"ADVISORY","url":"https://github.com/advisories/GHSA-6pcc-3rfx-4gpm"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r51f3f9801058e47153c0ad9bc6209d57a592fc0e7aefd787760911b8%40%3Cdev.velocity.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r91c64cd51e68e97d524395474eaa25362d564572276b9917fcbf5c32%40%3Cdev.velocity.apache.org%3E"},{"type":"REPORT","url":"https://github.com/dom4j/dom4j/issues/87"},{"type":"ADVISORY","url":"https://github.com/dom4j/dom4j/releases/tag/version-2.1.3"},{"type":"FIX","url":"https://github.com/dom4j/dom4j/commit/a8228522a99a02146106672a34c104adbda5c658"},{"type":"FIX","url":"https://github.com/dom4j/dom4j/commits/version-2.0.3"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2020-10683"},{"type":"ADVISORY","url":"https://github.com/advisories/GHSA-hwj3-m3p6-hj38"}],"affected":[{"package":{"name":"dom4j:dom4j","ecosystem":"Red Hat Lightwell:Maven","purl":"pkg:maven/dom4j/dom4j"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.6.1.rhlw-00004"}]}],"versions":["1.1","1.3","1.4","1.4-dev-2","1.4-dev-3","1.4-dev-4","1.4-dev-5","1.4-dev-6","1.4-dev-7","1.4-dev-8","1.5","1.5-beta-2","1.5-rc1","1.5.1","1.5.2","1.6","1.6.1"],"database_specific":{"lightwell":{"backport_base_version":"1.6.1","remediated_version":"1.6.1.rhlw-00004","repository_url":"https://packages.redhat.com/lightwell/java/remediated/"},"source":"https://github.com/project-lightwell/lightwell-osv/blob/main/advisories/RHLW-2026-f43b17f69a51feee.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N"}],"credits":[{"name":"Red Hat Lightwell","type":"REMEDIATION_DEVELOPER"}]}
