Hi,

The following vulnerability was published for node-xmldom.

CVE-2021-32796[0]:
| xmldom is an open source pure JavaScript W3C standard-based (XML DOM
| Level 2 Core) DOMParser and XMLSerializer module. xmldom versions
| 0.6.0 and older do not correctly escape special characters when
| serializing elements removed from their ancestor. This may lead to
| unexpected syntactic changes during XML processing in some downstream
| applications. This issue has been resolved in version 0.7.0. As a
| workaround downstream applications can validate the input and reject
| the maliciously crafted documents.


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