Summary
A flaw was found in xmldom, a JavaScript module for parsing and serializing XML. A remote attacker can exploit this vulnerability by providing a specially crafted `DocumentType.name` containing characters like `>` or whitespace.
This bypasses the `requireWellFormed` validation, allowing the injection of arbitrary XML markup. Such injection can lead to unintended modifications of the XML document structure, potentially resulting in arbitrary code execution or information disclosure within applications that process the affected XML.
