{"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":"xmldom is a pure JavaScript W3C standard-based (XML DOM Level 2 Core) `DOMParser` and `XMLSerializer` module. xmldom 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. This breaks the assumption that there is only a single root node in the tree, which led to issuance of CVE-2022-39299 as it is a potential issue for dependents. Update 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). As a workaround, please one of the following approaches depending on your use case: instead of searching for elements in the whole DOM, only search in the `documentElement`or reject a document with a document that has more then 1 `childNode`.","published":"2022-11-02T00:00:00Z","modified":"2026-08-12T03:51:44.286719291Z","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":null,"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"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:44.286719291Z"}}
