Description (CNA)
xmldom is a pure JavaScript W3C standard-based (XML DOM Level 2 Core) `DOMParser` and `XMLSerializer` module. In xmldom versions 0.6.0 and prior and @xmldom/xmldom prior to versions 0.8.12 and 0.9.9, xmldom/xmldom allows attacker-controlled strings containing the CDATA terminator ]]> to be inserted into a CDATASection node. During serialization, XMLSerializer emitted the CDATA content verbatim without rejecting or safely splitting the terminator. As a result, data intended to remain text-only became active XML markup in the serialized output, enabling XML structure injection and downstream business-logic manipulation. This issue has been patched in xmldom version 0.6.0 and @xmldom/xmldom versions 0.8.12 and 0.9.9.

No English description supplied.
A flaw was found in xmldom. A remote attacker can exploit this by inserting specific character sequences, known as the CDATA (Character Data) terminator ]]>, into a CDATASection node. When the XML is serialized, these sequences are not properly handled, allowing them to be interpreted as active XML markup. This vulnerability enables XML structure injection, which could lead to manipulation of the XML data and affect business logic.
