Details

xmldom allows multiple root nodes in a DOM ### Impact 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 https://nvd.nist.gov/vuln/detail/CVE-2022-39299 and is a potential issue for dependents. ### Patches 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`). ### Workarounds One of the following approaches might help, depending on your use case: - Instead of searching for elements in the whole DOM, only search in the `documentElement`. - Reject a document with a document that has more then 1 `childNode`. ### References - https://nvd.nist.gov/vuln/detail/CVE-2022-39299 - https://github.com/jindw/xmldom/issues/150 ### For more information If you have any questions or comments about this advisory: * Email us at security@xmldom.org
