Hi,

The following vulnerability was published for node-xmldom.

CVE-2022-39353[0]:
| 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@&gt;=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`.


If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
