  "title": "xmldom: XML injection through unvalidated DocumentType serialization",
  "description": "xmldom is a pure JavaScript W3C standard-based (XML DOM Level 2 Core) \u0060DOMParser\u0060 and \u0060XMLSerializer\u0060 module. In @xmldom/xmldom prior to versions 0.9.10 and 0.8.13 and xmldom version 0.6.0 and prior, the package serializes DocumentType node fields (internalSubset, publicId, systemId) verbatim without any escaping or validation. When these fields are set programmatically to attacker-controlled strings, XMLSerializer.serializeToString can produce output where the DOCTYPE declaration is terminated early and arbitrary markup appears outside it. This issue has been patched in versions @xmldom/xmldom versions 0.9.10 and 0.8.13.",
