DescriptionCVE.org

xmldom is a pure JavaScript W3C standard-based (XML DOM Level 2 Core) DOMParser and XMLSerializer module. Prior to @xmldom/xmldom versions 0.8.14 and 0.9.11, and in xmldom version 0.6.0 and earlier, Element.setAttribute() calls the private _createAttribute(name) path without validating the attribute name, while Document.createAttribute(name) validates against QName. XMLSerializer.serializeToString() emits attribute names verbatim, and requireWellFormed: true did not validate them, so a crafted name can terminate the intended attribute and inject additional attributes, including event handlers, into browser-consumed output; synthesized xmlns:PREFIX declarations expose the same unchecked-name boundary. This issue is fixed in @xmldom/xmldom versions 0.8.14 and 0.9.11; no fixed version is available for xmldom.

AnalysisAI

XML injection in the xmldom JavaScript library allows crafted attribute names to break out of attribute context during serialization, enabling injection of arbitrary attributes — including event handlers — into browser-consumed XML/HTML output. Applications using @xmldom/xmldom before 0.8.14 or 0.9.11, or any version of the legacy xmldom package (≤0.6.0), are affected when attacker-controlled data reaches Element.setAttribute() and the result is serialized via XMLSerializer.serializeToString(). …
