Security 2
  • XMLSerializer.serializeToString() (and Node.toString(), NodeList.toString()) now accept a requireWellFormed option that throws InvalidStateError for injection-prone node content when enabled, preventing XML injection via attacker-controlled node data
  • DOM traversal operations (XMLSerializer.serializeToString(), Node.prototype.normalize(), Node.prototype.cloneNode(true), Document.prototype.importNode(node, true), node.textContent getter, getElementsByTagName() / getElementsByTagNameNS() / getElementsByClassName() / getElementById()) are now iterative to prevent stack exhaustion on deeply nested DOM trees

  • 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.

  • 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()) are now iterative. Previously, deeply nested DOM trees would exhaust the JavaScript call stack and throw an unrecoverable RangeError. GHSA-2v35-w6hq-6mfw
