{"id":"CVE-2022-39353","aliases":["GHSA-crh6-fp67-6883"],"url":"https://o3.security/vulnerability/CVE-2022-39353","summary":"xmldom allows multiple root nodes in a DOM","details":"### Impact\nxmldom parses XML that is not well-formed because it contains multiple top level elements, and adds all root nodes to the `childNodes` collection of the `Document`, without reporting any error or throwing.\nThis breaks the assumption that there is only a single root node in the tree, which led to https://nvd.nist.gov/vuln/detail/CVE-2022-39299 and is a potential issue for dependents.\n\n### Patches\nUpdate to `@xmldom/xmldom@~0.7.7`, `@xmldom/xmldom@~0.8.4` (dist-tag `latest`) or `@xmldom/xmldom@>=0.9.0-beta.4` (dist-tag `next`).\n\n### Workarounds\nOne of the following approaches might help, depending on your use case:\n- Instead of searching for elements in the whole DOM, only search in the `documentElement`.\n- Reject a document with a document that has more then 1 `childNode`.\n\n### References\n- https://nvd.nist.gov/vuln/detail/CVE-2022-39299\n- https://github.com/jindw/xmldom/issues/150\n\n### For more information\nIf you have any questions or comments about this advisory:\n* Email us at security@xmldom.org\n","published":"2022-11-02T00:00:00Z","modified":"2026-10-28T02:30:58.467325796Z","cvss":{"score":9.4,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"npm","name":"xmldom","fixedVersion":null},{"ecosystem":"npm","name":"@xmldom/xmldom","fixedVersion":"0.7.7"},{"ecosystem":"npm","name":"@xmldom/xmldom","fixedVersion":"0.8.4"},{"ecosystem":"npm","name":"@xmldom/xmldom","fixedVersion":"0.9.0-beta.4"}],"fix":{"url":"https://github.com/xmldom/xmldom/commit/52a708360c35aa160fcca8621720d71fd0f95f1a","label":"xmldom/xmldom@52a7083"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/39xxx/CVE-2022-39353.json"},{"type":"ADVISORY","url":"https://github.com/xmldom/xmldom/security/advisories/GHSA-crh6-fp67-6883"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-39353"},{"type":"REPORT","url":"https://github.com/jindw/xmldom/issues/150"},{"type":"ARTICLE","url":"https://lists.debian.org/debian-lts-announce/2023/01/msg00000.html"},{"type":"WEB","url":"https://github.com/xmldom/xmldom/commit/52a708360c35aa160fcca8621720d71fd0f95f1a"},{"type":"WEB","url":"https://github.com/xmldom/xmldom/commit/7ff7c10ab2961703ac1752e95b4ff60ee4ee6643"},{"type":"WEB","url":"https://github.com/xmldom/xmldom/commit/c02f786216bed70825f9a351c65e61500f51e931"},{"type":"PACKAGE","url":"https://github.com/xmldom/xmldom"},{"type":"WEB","url":"https://github.com/xmldom/xmldom/releases/tag/0.7.7"},{"type":"WEB","url":"https://github.com/xmldom/xmldom/releases/tag/0.8.4"},{"type":"WEB","url":"https://github.com/xmldom/xmldom/releases/tag/0.9.0-beta.4"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-10-28T02:30:58.467325796Z"}}
