Summary
xmldom: Processing Instruction Target Injection Bypasses requireWellFormed
Details

Summary

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.

Details

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.

During serialization, the requireWellFormed code path (around line 3286) performs two checks on PI targets:

  1. Rejects targets containing : (namespace prefix check)
  2. Rejects targets matching xml case-insensitively (reserved prefix)

However, 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.

Root Cause

  1. createProcessingInstruction() performs no validation on target
  2. The serializer's requireWellFormed check is incomplete -- it only checks for : and xml, missing characters that break PI syntax (>, ?, whitespace)
  3. The serializer emits the target verbatim: <?${target} ${data}?>

Proof of Concept

const { DOMImplementation, XMLSerializer } = require('@xmldom/xmldom');

const impl = new DOMImplementation();
const serializer = new XMLSerializer();
const doc = impl.createDocument(null, 'root', null);

// PI target containing > breaks the PI boundary
const pi = doc.createProcessingInstruction('a>', 'data');
doc.documentElement.appendChild(pi);

const output = serializer.serializeToString(doc, { requireWellFormed: true });
console.log(output);
// Output: <root><?a> data?></root>
//
// The > in the target closes the PI prematurely.
// A downstream XML parser sees:
//   - Processing instruction: <?a?>  (target "a", no data)
//   - Text content: " data?>"
//
// requireWellFormed: true did NOT prevent the injection.

Injecting elements via PI target

const pi2 = doc.createProcessingInstruction(
  'a?><script xmlns="http://www.w3.org/1999/xhtml">alert(1)</script><?b',
  ''
);
doc.documentElement.appendChild(pi2);

const output2 = serializer.serializeToString(doc, { requireWellFormed: true });
console.log(output2);
// Output includes:
//   <?a?><script xmlns="http://www.w3.org/1999/xhtml">alert(1)</script><?b ?>
//
// The injected <script> element is valid XHTML that a browser would execute.

Impact

Applications that create processing instructions with user-controlled target strings and serialize the result are vulnerable to XML injection. This enables:

  • XML structure injection: Breaking the PI boundary to inject arbitrary elements, text, or additional processing instructions into the output
  • XSS via XHTML: If the serialized output is served as XHTML or processed by a browser-based XML parser, injected script elements will execute
  • XXE chain: Injected DOCTYPE declarations or entity references could trigger XXE in downstream XML parsers that consume the output
  • requireWellFormed bypass: The existing well-formedness checks are incomplete and provide a false sense of security

Fix Applied

Under 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.\ On 0.9.12 this replaces an earlier check that already rejected a colon or xml, so the no-colon rule is preserved.\ 0.8.15 had no processing-instruction target check at all, so the whole target validation is new there.\ Non-breaking and opt-in. See the XML Name production.

⚠ Opt-in required. Protection is not automatic. Existing serialization calls remain vulnerable unless { requireWellFormed: true } is explicitly passed. Applications that serialize untrusted DOM content should audit all serializeToString() call sites and add it.

Proof of Concept - fixed path

const { DOMImplementation, XMLSerializer } = require('@xmldom/xmldom');

const impl = new DOMImplementation();
const serializer = new XMLSerializer();
const doc = impl.createDocument(null, 'root', null);

// PI target containing > breaks the PI boundary
const pi = doc.createProcessingInstruction('a>', 'data');
doc.documentElement.appendChild(pi);

// Default path: emits the ill-formed target verbatim.
console.log(serializer.serializeToString(doc));
// Output: <root><?a> data?></root>

// Opt-in path: the target check now rejects the break-out character.
try {
  serializer.serializeToString(doc, { requireWellFormed: true });
} catch (e) {
  console.log(e.name); // InvalidStateError
}

Why the default stays verbatim

W3C 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 and XML Processing Instructions.)

Residual limitation

The 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.

GHSA-F6WW-3GGP-FR8H

Vulnerability from github – Published: 2026-04-22 20:19 – Updated: 2026-05-08 20:10
VLAI
Summary
xmldom has XML injection through unvalidated DocumentType serialization
Details

Summary

The package serializes DocumentType node fields (internalSubset, publicId, systemId) verbatim without any escaping or validation. When these fields are set programmatically to attacker-controlled strings, XMLSerializer.serializeToString can produce output where the DOCTYPE declaration is terminated early and arbitrary markup appears outside it.


Details

DOMImplementation.createDocumentType(qualifiedName, publicId, systemId, internalSubset) validates only qualifiedName against the XML QName production. The remaining three arguments are stored as-is with no validation.

The XMLSerializer emits DocumentType nodes as:

<!DOCTYPE name[ PUBLIC pubid][ SYSTEM sysid][ [internalSubset]]>

All fields are pushed into the output buffer verbatim — no escaping, no quoting added.

internalSubset injection: The serializer wraps internalSubset with [ and ]. A value containing ]> closes the internal subset and the DOCTYPE declaration at the injection point. Any content after ]> in internalSubset appears outside the DOCTYPE in the serialized output as raw XML markup. Reported by @TharVid (GHSA-f6ww-3ggp-fr8h). Affected: @xmldom/xmldom ≥ 0.9.0 via createDocumentType API; 0.8.x only via direct property write.

publicId injection: The serializer emits publicId verbatim after PUBLIC with no quoting added. A value containing an injected system identifier (e.g., "pubid" SYSTEM "evil") breaks the intended quoting context, injecting a fake SYSTEM entry into the serialized DOCTYPE declaration. Identified during internal security research. Affected: both branches, all versions back to 0.1.0.

systemId injection: The serializer emits systemId verbatim. A value containing > terminates the DOCTYPE declaration early; content after > appears as raw XML markup outside the DOCTYPE context. Identified during internal security research. Affected: both branches, all versions back to 0.1.0.

The parse path is safe: the SAX parser enforces the PubidLiteral and SystemLiteral grammar productions, which exclude the relevant characters, and the internal subset parser only accepts a subset it can structurally validate. The vulnerability is reachable only through programmatic createDocumentType calls with attacker-controlled arguments.


Affected code

lib/dom.jscreateDocumentType (lines 898–910):

createDocumentType: function (qualifiedName, publicId, systemId, internalSubset) {
    validateQualifiedName(qualifiedName);          // only qualifiedName is validated
    var node = new DocumentType(PDC);
    node.name = qualifiedName;
    node.nodeName = qualifiedName;
    node.publicId = publicId || '';               // stored verbatim
    node.systemId = systemId || '';               // stored verbatim
    node.internalSubset = internalSubset || '';   // stored verbatim
    node.childNodes = new NodeList();
    return node;
},

lib/dom.js — serializer DOCTYPE case (lines 2948–2964):

case DOCUMENT_TYPE_NODE:
    var pubid = node.publicId;
    var sysid = node.systemId;
    buf.push(g.DOCTYPE_DECL_START, ' ', node.name);
    if (pubid) {
        buf.push(' ', g.PUBLIC, ' ', pubid);
        if (sysid && sysid !== '.') {
            buf.push(' ', sysid);
        }
    } else if (sysid && sysid !== '.') {
        buf.push(' ', g.SYSTEM, ' ', sysid);
    }
    if (node.internalSubset) {
        buf.push(' [', node.internalSubset, ']');  // internalSubset emitted verbatim
    }
    buf.push('>');
    return;

PoC

internalSubset injection

const { DOMImplementation, XMLSerializer } = require('@xmldom/xmldom');

const impl = new DOMImplementation();
const doctype = impl.createDocumentType(
    'root',
    '',
    '',
    ']><injected/><![CDATA['
);
const doc = impl.createDocument(null, 'root', doctype);
const xml = new XMLSerializer().serializeToString(doc);
console.log(xml);
// <!DOCTYPE root []><injected/><![CDATA[]><root/>
//                   ^^^^^^^^^^  injected element outside DOCTYPE

publicId quoting context break

const { DOMImplementation, XMLSerializer } = require('@xmldom/xmldom');

const impl = new DOMImplementation();
const doctype = impl.createDocumentType(
    'root',
    '"injected PUBLIC_ID" SYSTEM "evil"',
    '',
    ''
);
const doc = impl.createDocument(null, 'root', doctype);
console.log(new XMLSerializer().serializeToString(doc));
// <!DOCTYPE root PUBLIC "injected PUBLIC_ID" SYSTEM "evil"><root/>
// quoting context broken — SYSTEM entry injected

systemId injection

const { DOMImplementation, XMLSerializer } = require('@xmldom/xmldom');

const impl = new DOMImplementation();
const doctype = impl.createDocumentType(
    'root',
    '',
    '"sysid"><injected attr="pwn"/>',
    ''
);
const doc = impl.createDocument(null, 'root', doctype);
console.log(new XMLSerializer().serializeToString(doc));
// <!DOCTYPE root SYSTEM "sysid"><injected attr="pwn"/>><root/>
// > in sysid closes DOCTYPE early; <injected/> appears as sibling element

Impact

An application that programmatically constructs DocumentType nodes from user-controlled data and then serializes the document can emit a DOCTYPE declaration where the internal subset is closed early or where injected SYSTEM entities or other declarations appear in the serialized output.

Downstream XML parsers that re-parse the serialized output and expand entities from the injected DOCTYPE declarations may be susceptible to XXE-class attacks if they enable entity expansion.


Fix Applied

⚠ Opt-in required. Protection is not automatic. Existing serialization calls remain vulnerable unless { requireWellFormed: true } is explicitly passed. Applications that pass untrusted data to createDocumentType() or write untrusted values directly to a DocumentType node's publicId, systemId, or internalSubset properties should audit all serializeToString() call sites and add the option.

XMLSerializer.serializeToString() now accepts an options object as a second argument. When { requireWellFormed: true } is passed, the serializer validates the DocumentType node's publicId, systemId, and internalSubset fields before emitting the DOCTYPE declaration and throws InvalidStateError if any field contains an injection sequence:

  • publicId: throws if non-empty and does not match the XML PubidLiteral production (XML 1.0 [12])
  • systemId: throws if non-empty and does not match the XML SystemLiteral production (XML 1.0 [11])
  • internalSubset: throws if it contains ]> (which closes the internal subset and DOCTYPE declaration early)

All three checks apply regardless of how the invalid value entered the node — whether via createDocumentType arguments or a subsequent direct property write.

PoC — fixed path

const { DOMImplementation, XMLSerializer } = require('@xmldom/xmldom');
const impl = new DOMImplementation();

// internalSubset injection
const dt1 = impl.createDocumentType('root', '', '', ']><injected/><![CDATA[');
const doc1 = impl.createDocument(null, 'root', dt1);

// Default (unchanged): verbatim — injection present
console.log(new XMLSerializer().serializeToString(doc1));
// <!DOCTYPE root []><injected/><![CDATA[]><root/>

// Opt-in guard: throws InvalidStateError
try {
  new XMLSerializer().serializeToString(doc1, { requireWellFormed: true });
} catch (e) {
  console.log(e.name, e.message);
  // InvalidStateError: DocumentType internalSubset contains "]>"
}

The guard also covers post-creation property writes:

const dt2 = impl.createDocumentType('root', '', '');
dt2.systemId = '"sysid"><injected attr="pwn"/>';
const doc2 = impl.createDocument(null, 'root', dt2);
new XMLSerializer().serializeToString(doc2, { requireWellFormed: true });
// InvalidStateError: DocumentType systemId is not a valid SystemLiteral

Why the default stays verbatim

The W3C DOM Parsing and Serialization spec §3.2.1.3 defines a require well-formed flag whose default value is false. With the flag unset, the spec permits verbatim serialization of DOCTYPE fields. Unconditionally throwing would be a behavioral breaking change with no spec justification. The opt-in requireWellFormed: true flag allows applications that require injection safety to enable strict mode without breaking existing deployments.

Residual limitation

createDocumentType(qualifiedName, publicId, systemId[, internalSubset]) does not validate publicId, systemId, or internalSubset at creation time. This creation-time validation is a breaking change and is deferred to a future breaking release.

When the default serialization path is used (without requireWellFormed: true), all three fields are still emitted verbatim. Applications that do not pass requireWellFormed: true remain exposed.

The vulnerability is reachable only through programmatic\n`createDocumentType` calls with attacker-controlled arguments.\n\n---\n\n## Affected code\n\n**`lib/dom.js` \u2014 `createDocumentType` (lines 898\u2013910):**\n\n```js\ncreateDocumentType: function (qualifiedName, publicId, systemId, internalSubset) {\n    validateQualifiedName(qualifiedName);          // only qualifiedName is validated\n    var node = new DocumentType(PDC);\n    node.name = qualifiedName;\n    node.nodeName = qualifiedName;\n    node.publicId = publicId || \u0027\u0027;               // stored verbatim\n    node.systemId = systemId || \u0027\u0027;               // stored verbatim\n    node.internalSubset = internalSubset || \u0027\u0027;   // stored verbatim\n    node.childNodes = new NodeList();\n    return node;\n},\n```\n\n**`lib/dom.js` \u2014 serializer DOCTYPE case (lines 2948\u20132964):**\n\n```js\ncase DOCUMENT_TYPE_NODE:\n    var pubid = node.publicId;\n    var sysid = node.systemId;\n    buf.push(g.DOCTYPE_DECL_START, \u0027 \u0027, node.name);\n    if (pubid) {\n        buf.push(\u0027 \u0027, g.PUBLIC, \u0027 \u0027, pubid);\n        if (sysid \u0026\u0026 sysid !== \u0027.\u0027) {\n            buf.push(\u0027 \u0027, sysid);\n        }\n    } else if (sysid \u0026\u0026 sysid !== \u0027.\u0027) {\n        buf.push(\u0027 \u0027, g.SYSTEM, \u0027 \u0027, sysid);\n    }\n    if (node.internalSubset) {\n        buf.push(\u0027 [\u0027, node.internalSubset, \u0027]\u0027);  // internalSubset emitted verbatim\n    }\n    buf.push(\u0027\u003e\u0027);\n    return;\n```\n\n---\n\n## PoC\n\n### internalSubset injection\n\n```js\nconst { DOMImplementation, XMLSerializer } = require(\u0027@xmldom/xmldom\u0027);\n\nconst impl = new DOMImplementation();\nconst doctype = impl.createDocumentType(\n    \u0027root\u0027,\n    \u0027\u0027,\n    \u0027\u0027,\n    \u0027]\u003e\u003cinjected/\u003e\u003c![CDATA[\u0027\n);\nconst doc = impl.createDocument(null, \u0027root\u0027, doctype);\nconst xml = new XMLSerializer().serializeToString(doc);\nconsole.log(xml);\n// \u003c!DOCTYPE root []\u003e\u003cinjected/\u003e\u003c![CDATA[]\u003e\u003croot/\u003e\n//                   ^^^^^^^^^^  injected element outside DOCTYPE\n```\n\n### publicId quoting context break\n\n```js\nconst { DOMImplementation, XMLSerializer } = require(\u0027@xmldom/xmldom\u0027);\n\nconst impl = new DOMImplementation();\nconst doctype = impl.createDocumentType(\n    \u0027root\u0027,\n    \u0027\"injected PUBLIC_ID\" SYSTEM \"evil\"\u0027,\n    \u0027\u0027,\n    \u0027\u0027\n);\nconst doc = impl.createDocument(null, \u0027root\u0027, doctype);\nconsole.log(new XMLSerializer().serializeToString(doc));\n// \u003c!DOCTYPE root PUBLIC \"injected PUBLIC_ID\" SYSTEM \"evil\"\u003e\u003croot/\u003e\n// quoting context broken \u2014 SYSTEM entry injected\n```\n\n### systemId injection\n\n```js\nconst { DOMImplementation, XMLSerializer } = require(\u0027@xmldom/xmldom\u0027);\n\nconst impl = new DOMImplementation();\nconst doctype = impl.createDocumentType(\n    \u0027root\u0027,\n    \u0027\u0027,\n    \u0027\"sysid\"\u003e\u003cinjected attr=\"pwn\"/\u003e\u0027,\n    \u0027\u0027\n);\nconst doc = impl.createDocument(null, \u0027root\u0027, doctype);\nconsole.log(new XMLSerializer().serializeToString(doc));\n// \u003c!DOCTYPE root SYSTEM \"sysid\"\u003e\u003cinjected attr=\"pwn\"/\u003e\u003e\u003croot/\u003e\n// \u003e in sysid closes DOCTYPE early; \u003cinjected/\u003e appears as sibling element\n```\n\n---\n\n## Impact\n\nAn application that programmatically constructs `DocumentType` nodes from user-controlled data and\nthen serializes the document can emit a DOCTYPE declaration where the internal subset is closed\nearly or where injected SYSTEM entities or other declarations appear in the serialized output.\n\nDownstream XML parsers that re-parse the serialized output and expand entities from the injected\nDOCTYPE declarations may be susceptible to XXE-class attacks if they enable entity expansion.\n\n---\n\n## Fix Applied\n\n\u003e **\u26a0 Opt-in required.** Protection is not automatic. Existing serialization calls remain\n\u003e vulnerable unless `{ requireWellFormed: true }` is explicitly passed. Applications that pass\n\u003e untrusted data to `createDocumentType()` or write untrusted values directly to a\n\u003e `DocumentType` node\u0027s `publicId`, `systemId`, or `internalSubset` properties should audit\n\u003e all `serializeToString()` call sites and add the option.\n\n`XMLSerializer.serializeToString()` now accepts an options object as a second argument. When `{ requireWellFormed: true }` is passed, the serializer validates the `DocumentType` node\u0027s `publicId`, `systemId`, and `internalSubset` fields before emitting the DOCTYPE declaration and throws `InvalidStateError` if any field contains an injection sequence:\n\n- **`publicId`**: throws if non-empty and does not match the XML `PubidLiteral` production (XML 1.0 [12])\n- **`systemId`**: throws if non-empty and does not match the XML `SystemLiteral` production (XML 1.0 [11])\n- **`internalSubset`**: throws if it contains `]\u003e` (which closes the internal subset and DOCTYPE declaration early)\n\nAll three checks apply regardless of how the invalid value entered the node \u2014 whether via `createDocumentType` arguments or a subsequent direct property write.\n\n### PoC \u2014 fixed path\n\n```js\nconst { DOMImplementation, XMLSerializer } = require(\u0027@xmldom/xmldom\u0027);\nconst impl = new DOMImplementation();\n\n// internalSubset injection\nconst dt1 = impl.createDocumentType(\u0027root\u0027, \u0027\u0027, \u0027\u0027, \u0027]\u003e\u003cinjected/\u003e\u003c![CDATA[\u0027);\nconst doc1 = impl.createDocument(null, \u0027root\u0027, dt1);\n\n// Default (unchanged): verbatim \u2014 injection present\nconsole.log(new XMLSerializer().serializeToString(doc1));\n// \u003c!DOCTYPE root []\u003e\u003cinjected/\u003e\u003c![CDATA[]\u003e\u003croot/\u003e\n\n// Opt-in guard: throws InvalidStateError\ntry {\n  new XMLSerializer().serializeToString(doc1, { requireWellFormed: true });\n} catch (e) {\n  console.log(e.name, e.message);\n  // InvalidStateError: DocumentType internalSubset contains \"]\u003e\"\n}\n```\n\nThe guard also covers post-creation property writes:\n\n```js\nconst dt2 = impl.createDocumentType(\u0027root\u0027, \u0027\u0027, \u0027\u0027);\ndt2.systemId = \u0027\"sysid\"\u003e\u003cinjected attr=\"pwn\"/\u003e\u0027;\nconst doc2 = impl.createDocument(null, \u0027root\u0027, dt2);\nnew XMLSerializer().serializeToString(doc2, { requireWellFormed: true });\n// InvalidStateError: DocumentType systemId is not a valid SystemLiteral\n```\n\n### Why the default stays verbatim\n\nThe W3C DOM Parsing and Serialization spec \u00a73.2.1.3 defines a `require well-formed` flag whose **default value is `false`**. With the flag unset, the spec permits verbatim serialization of DOCTYPE fields. Unconditionally throwing would be a behavioral breaking change with no spec justification. The opt-in `requireWellFormed: true` flag allows applications that require injection safety to enable strict mode without breaking existing deployments.\n\n### Residual limitation\n\n`createDocumentType(qualifiedName, publicId, systemId[, internalSubset])` does not validate `publicId`, `systemId`, or `internalSubset` at creation time. This creation-time validation is a breaking change and is deferred to a future breaking release.\n\nWhen the default serialization path is used (without `requireWellFormed: true`), all three fields are still emitted verbatim. Applications that do not pass `requireWellFormed: true` remain exposed.",

Mitigation MIT-5
Implementation

Strategy: Input Validation

  • Assume all input is malicious. Use an "accept known good" input validation strategy, i.e., use a list of acceptable inputs that strictly conform to specifications. Reject any input that does not strictly conform to specifications, or transform it into something that does.
  • When performing input validation, consider all potentially relevant properties, including length, type of input, the full range of acceptable values, missing or extra inputs, syntax, consistency across related fields, and conformance to business rules. As an example of business rule logic, "boat" may be syntactically valid because it only contains alphanumeric characters, but it is not valid if the input is only expected to contain colors such as "red" or "blue."
  • Do not rely exclusively on looking for malicious or malformed inputs. This is likely to miss at least one undesirable input, especially if the code's environment changes. This can give attackers enough room to bypass the intended validation. However, denylists can be useful for detecting potential attacks or determining which inputs are so malformed that they should be rejected outright.
CAPEC-250: XML Injection

An attacker utilizes crafted XML user-controllable input to probe, attack, and inject data into the XML database, using techniques similar to SQL injection. The user-controllable input can allow for unauthorized viewing of data, bypassing authentication or the front-end application for direct XML database access, and possibly altering database information.

CAPEC-83: XPath Injection

An attacker can craft special user-controllable input consisting of XPath expressions to inject the XML database and bypass authentication or glean information that they normally would not be able to. XPath Injection enables an attacker to talk directly to the XML database, thus bypassing the application completely. XPath Injection results from the failure of an application to properly sanitize input used as part of dynamic XPath expressions used to query an XML database.
