0.9.10

Commits

Fixed

• Security: XMLSerializer.serializeToString() (and Node.toString(), NodeList.toString()) now accept a requireWellFormed option. When { requireWellFormed: true } is passed, the serializer throws InvalidStateError for injection-prone node content, preventing XML injection via attacker-controlled node data. GHSA-j759-j44w-7fr8 GHSA-x6wf-f3px-wcqx GHSA-f6ww-3ggp-fr8h
  • Comment: throws when data contains -- anywhere, ends with -, or contains characters outside the XML Char production
  • ProcessingInstruction: throws when target contains : or matches xml (case-insensitive), or data contains characters outside the XML Char production or contains ?>
  • DocumentType: throws when publicId fails PubidLiteral, systemId fails SystemLiteral, or internalSubset contains ]>
• Security: DOM traversal operations (XMLSerializer.serializeToString(), Node.prototype.normalize(), Node.prototype.cloneNode(true), Document.prototype.importNode(node, true), node.textContent getter, getElementsByTagName() / getElementsByTagNameNS() / getElementsByClassName() / getElementById(), Node.prototype.isEqualNode()) are now iterative. Previously, deeply nested DOM trees would exhaust the JavaScript call stack and throw an unrecoverable RangeError. GHSA-2v35-w6hq-6mfw
• isEqualNode now correctly returns false for CDATASection nodes with different data

Deprecated

• The splitCDATASections serializer option is deprecated and will be removed in the next breaking release. The automatic splitting of "]]>" in CDATASection data was introduced as a workaround; use requireWellFormed: true or ensure CDATASection data does not contain "]]>" before serialization.

Chore

0.8.13

Fixed

• Security: XMLSerializer.serializeToString() (and Node.toString(), NodeList.toString()) now accept a requireWellFormed option (fourth argument, after isHtml and nodeFilter). When { requireWellFormed: true } is passed, the serializer throws InvalidStateError for injection-prone node content, preventing XML injection via attacker-controlled node data.
