The Ubuntu security team deemed this advisory irrelevant for Ubuntu:22.10.
NVD Description
Note: Versions mentioned in the description apply only to the upstream node-xmldom package and not the node-xmldom package as distributed by Ubuntu.
xmldom is a pure JavaScript W3C standard-based (XML DOM Level 2 Core) DOMParser and XMLSerializer module. xmldom versions 0.4.0 and older do not correctly preserve system identifiers, FPIs or namespaces when repeatedly parsing and serializing maliciously crafted documents. This may lead to unexpected syntactic changes during XML processing in some downstream applications. This is fixed in version 0.5.0. As a workaround downstream applications can validate the input and reject the maliciously crafted documents.
