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
.
