GHSA-2V35-W6HQ-6MFW
Vulnerability from github – Published: 2026-04-22 20:23 – Updated: 2026-05-08 20:10Summary
Seven recursive traversals in lib/dom.js operate without a depth limit. A sufficiently deeply
nested DOM tree causes a RangeError: Maximum call stack size exceeded, crashing the application.
Reported operations:
- Node.prototype.normalize() — reported by @praveen-kv (email 2026-04-05) and @KarimTantawey (GHSA-fwmp-8wwc-qhv6, via DOMParser.parseFromString())
- XMLSerializer.serializeToString() — reported by @Jvr2022 (GHSA-2v35-w6hq-6mfw) and @KarimTantawey (GHSA-j2hf-fqwf-rrjf)
Additionally, discovered in research:
- Element.getElementsByTagName() / getElementsByTagNameNS() / getElementsByClassName() / getElementById()
- Node.cloneNode(true)
- Document.importNode(node, true)
- node.textContent (getter)
- Node.isEqualNode(other)
All seven share the same root cause: pure-JavaScript recursive tree traversal with no depth guard. A single deeply nested document (parsed successfully) triggers any or all of these operations.
Details
Root cause
lib/dom.js implements DOM tree traversals as depth-first recursive functions. Each level of
element nesting adds one JavaScript call frame. The JS engine's call stack is finite; once
exhausted, a RangeError: Maximum call stack size exceeded is thrown. This error may not be
caught reliably at stack-exhaustion depths because the catch handler itself requires stack
frames to execute — especially in async scenarios, where an uncaught RangeError inside a
callback or promise chain can crash the entire Node.js process.
Parsing a deeply nested document succeeds — the SAX parser in lib/sax.js is iterative.
The crash occurs during subsequent operations on the parsed DOM.
Node.prototype.normalize() — reported by @praveen-kv
lib/dom.js:1296–1308 (main):
normalize: function () {
var child = this.firstChild;
while (child) {
var next = child.nextSibling;
if (next && next.nodeType == TEXT_NODE && child.nodeType == TEXT_NODE) {
this.removeChild(next);
child.appendData(next.data);
} else {
child.normalize(); // recursive call — no depth guard
child = next;
}
}
},
Crash threshold (Node.js 18, default stack): ~10,000 levels.
XMLSerializer.serializeToString() — reported by @Jvr2022
lib/dom.js:2790–2974 (main):
The internal serializeToString worker recurses into child nodes at four call sites, each
passing a visibleNamespaces.slice() copy. The per-frame allocation causes earlier stack
exhaustion than normalize().
Crash threshold (Node.js 18, default stack): ~5,000 levels.
Additional recursive entry points
All five crash at ~10,000 levels on Node.js 18.
| Function | Definition | Public API entry point(s) | Crash depth (Node.js 18) |
|---|---|---|---|
_visitNode |
lib/dom.js:1529 |
getElementsByTagName(), getElementsByTagNameNS(), getElementsByClassName(), getElementById() |
~10,000 levels |
cloneNode (module fn) |
lib/dom.js:3037 |
Node.prototype.cloneNode(true) |
~10,000 levels |
importNode (module fn) |
lib/dom.js:2975 |
Document.prototype.importNode(node, true) |
~10,000 levels |
getTextContent (inner fn) |
lib/dom.js:3130 |
node.textContent (getter) |
~10,000 levels |
isEqualNode |
lib/dom.js:1120 |
Node.prototype.isEqualNode(other) |
~10,000 levels |
Both active branches (main and release-0.8.x) are identically affected. The unscoped xmldom
package (≤ 0.6.0) carries the same recursive patterns from its initial commit.
Browser behavior
Tested with Chromium 147 (Playwright headless). Chromium's native C++ implementations of all seven DOM methods are iterative — they traverse the DOM without consuming JS call stack frames. All seven succeed at depths up to 20,000 without any crash.
When @xmldom/xmldom is bundled and run in a browser context the same recursive JS code executes
under the browser's V8 stack limit (~12,000–13,000 frames). The crash thresholds are similar to
those observed on Node.js 18 (~5,000 for serializeToString, ~10,000 for the remaining six).
The vulnerability is specific to xmldom's pure-JavaScript recursive implementation, not an inherent property of the DOM operations.
PoC
normalize() (from @praveen-kv report, 2026-04-05)
const { DOMParser } = require('@xmldom/xmldom');
function generateNestedXML(depth) {
return '<root>' + '<a>'.repeat(depth) + 'text' + '</a>'.repeat(depth) + '</root>';
}
const doc = new DOMParser().parseFromString(generateNestedXML(10000), 'text/xml');
doc.documentElement.normalize();
// RangeError: Maximum call stack size exceeded
XMLSerializer.serializeToString() (from GHSA-2v35-w6hq-6mfw)
const { DOMParser, XMLSerializer } = require('@xmldom/xmldom');
const depth = 5000;
const xml = '<a>'.repeat(depth) + '</a>'.repeat(depth);
const doc = new DOMParser().parseFromString(xml, 'text/xml');
new XMLSerializer().serializeToString(doc);
// RangeError: Maximum call stack size exceeded
The other methods have been verified using similar pocs.
Impact
Any service that accepts attacker-controlled XML and subsequently calls any of the seven affected DOM operations can be forced into a reliable denial of service with a single crafted payload.
The immediate result is an uncaught RangeError and failed request processing. In deployments
where uncaught exceptions terminate the worker or process, the impact can extend beyond a single
request and disrupt service availability more broadly.
No authentication, special options, or invalid XML is required. A valid, deeply nested XML document is enough.
Disclosure
The normalize() vector was publicly disclosed at 2026-04-06T11:25:07Z via
xmldom/xmldom#987 (closed without merge).
serializeToString() and the five additional recursive entry points were not mentioned in that PR.
Fix Applied
All seven affected traversals have been converted from recursive to iterative implementations, eliminating call-stack consumption on deep trees.
walkDOM utility
A new walkDOM(node, context, callbacks) utility is introduced. It traverses the subtree rooted at node in depth-first order using an explicit JavaScript array as a stack, consuming heap memory instead of call-stack frames. context is an arbitrary value threaded through the walk — each callbacks.enter(node, context) call returns the context to pass to that node's children, enabling per-branch state (e.g. namespace snapshots in the serializer). callbacks.exit(node, context) (optional) is called in post-order after all children have been visited.
The following six operations are re-implemented on top of walkDOM:
| Operation | Public entry point(s) |
|---|---|
_visitNode helper |
getElementsByTagName(), getElementsByTagNameNS(), getElementsByClassName(), getElementById() |
getTextContent inner function |
node.textContent getter |
cloneNode module function |
Node.prototype.cloneNode(true) |
importNode module function |
Document.prototype.importNode(node, true) |
serializeToString worker |
XMLSerializer.prototype.serializeToString(), Node.prototype.toString(), NodeList.prototype.toString() |
normalize |
Node.prototype.normalize() |
normalize uses walkDOM with a null context and an enter callback that merges adjacent Text children of the current node before walkDOM reads and queues those children — so the surviving post-merge children are what the walker descends into.
Custom iterative loop for isEqualNode
One function cannot use walkDOM:
Node.prototype.isEqualNode(other) (0.9.x only; absent from 0.8.x) compares two trees in parallel. It maintains an explicit stack of {node, other} node pairs — one node from each tree — which cannot be expressed with walkDOM's single-tree visitor.
After the fix
All seven entry points succeed on trees of arbitrary depth without throwing RangeError. The original PoCs still demonstrate the vulnerability on unpatched versions and confirm the fix on patched versions.

Vulnerability from csaf_redhat - Published: 2026-06-16 09:33 - Updated: 2026-06-16 23:10A flaw was found in fast-uri. A remote attacker could exploit this vulnerability by providing a specially crafted Uniform Resource Locator (URL) containing percent-encoded path separators and dot segments. Due to incorrect processing, fast-uri would decode these elements before proper normalization, leading to distinct URLs resolving to the same internal path. This could allow an attacker to bypass security policies that rely on path-based comparisons, potentially gaining unauthorized access to resources.

A flaw was found in fast-uri. A remote attacker could exploit this vulnerability by crafting a malicious Uniform Resource Identifier (URI) that contains percent-encoded authority delimiters. The fast-uri library incorrectly decodes these delimiters during normalization and then re-emits them as raw separators, which can change the URI's intended authority. This issue allows applications that perform host allowlist checks, redirect validation, or outbound request routing to be steered to a different authority than specified, potentially bypassing security controls.

A flaw was found in the shell-quote component. The quote() function did not properly validate object-token inputs, allowing line terminators to pass unescaped into the output. A remote attacker could exploit this vulnerability by providing specially crafted input, which a POSIX shell would interpret as a command separator. This could lead to command injection, enabling the attacker to execute arbitrary code on the system.

A flaw was found in Axios, a promise-based HTTP client for browsers and Node.js. This vulnerability occurs because the `toFormData` function recursively processes nested objects without a depth limit. A remote attacker can exploit this by sending deeply nested request data, which causes the Node.js process to crash due to a RangeError, leading to a potential Denial of Service (DoS) if the process crashes.

A flaw was found in Axios, a promise-based HTTP client. This vulnerability, a Prototype Pollution "Gadget" attack, allows an attacker to manipulate the `Object.prototype.validateStatus` property. By polluting this property, all HTTP error responses (such as 401, 403, or 500) are silently treated as successful responses. This can lead to a complete bypass of application-level authentication and error handling, potentially granting unauthorized access.

A flaw was found in Axios, a promise-based HTTP client. An attacker who can control the destination address of an Axios request can exploit this vulnerability. By using specific internal network addresses (within the 127.0.0.0/8 range, excluding 127.0.0.1), the attacker can completely bypass the NO_PROXY protection, potentially leading to unauthorized access or information disclosure within the network. This issue is an incomplete fix for a previous vulnerability.

A flaw was found in Axios, a widely used HTTP client. This vulnerability, known as a Prototype Pollution "Gadget" attack, allows a remote attacker to subtly alter JSON API responses. By manipulating a specific function, an attacker can selectively modify data within these responses. This could lead to significant security breaches, including unauthorized privilege escalation, fraudulent balance manipulation, or bypassing critical authorization checks.

A flaw was found in protobufjs, a library used to compile protobuf definitions into JavaScript functions. A remote attacker could exploit this vulnerability by providing a crafted descriptor that includes a non-string default value for a bytes field. This could lead to the generation of an unsafe expression within the toObject conversion function, ultimately allowing the attacker to execute arbitrary code.
