CyberRota Analysis
AI-GeneratedThe vulnerability affects the xmldom module in JavaScript, specifically versions prior to 0.8.15 and 0.9.12, as well as xmldom version 0.6.0 and earlier. It allows for the creation of invalid entity references that can lead to the generation of attacker-controlled XML markup when serialized, potentially compromising the integrity of XML data. Developers and organizations using affected versions should prioritize updating to the fixed versions to mitigate the risk of exploitation.

Original NVD Description
xmldom is a pure JavaScript W3C standard-based (XML DOM Level 2 Core) DOMParser and XMLSerializer module. Prior to @xmldom/xmldom versions 0.8.15 and 0.9.12, and in xmldom version 0.6.0 and earlier, Document.createEntityReference(name) accepts an invalid name and the ENTITY_REFERENCE_NODE serializer emits the resulting nodeName directly in &name; form. Directly serializing the node or fragment with XMLSerializer.serializeToString() and requireWellFormed: true can therefore break the entity-reference boundary and produce attacker-controlled XML markup when reparsed. The parser does not ordinarily create these nodes, and element-child insertion is rejected, so exploitation requires an application to create and directly serialize an EntityReference. This issue is fixed in @xmldom/xmldom versions 0.8.15 and 0.9.12; no fixed version is available for xmldom.
