Notable Changes
Corepack

Node.js now includes Corepack, a script that acts as a bridge between Node.js projects and the package managers they are intended to be used with during development. In practical terms, Corepack will let you use Yarn and pnpm without having to install them - just like what currently happens with npm, which is shipped in Node.js by default. Please head over to the Corepack documentation page for more information on how to use it.

Notable changes
Improper handling of URI Subject Alternative Names (Medium)(CVE-2021-44531)

Accepting arbitrary Subject Alternative Name (SAN) types, unless a PKI is specifically defined to use a particular SAN type, can result in bypassing name-constrained intermediates. Node.js was accepting URI SAN types, which PKIs are often not defined to use. Additionally, when a protocol allows URI SANs, Node.js did not match the URI correctly.

Versions of Node.js with the fix for this disable the URI SAN type when checking a certificate against a hostname. This behavior can be reverted through the --security-revert command-line option.

More details will be available at CVE-2021-44531 after publication.

Certificate Verification Bypass via String Injection (Medium)(CVE-2021-44532)

Node.js converts SANs (Subject Alternative Names) to a string format. It uses this string to check peer certificates against hostnames when validating connections. The string format was subject to an injection vulnerability when name constraints were used within a certificate chain, allowing the bypass of these name constraints.

Versions of Node.js with the fix for this escape SANs containing the problematic characters in order to prevent the injection. This behavior can be reverted through the --security-revert command-line option.

More details will be available at CVE-2021-44532 after publication.

Incorrect handling of certificate subject and issuer fields (Medium)(CVE-2021-44533)

Node.js did not handle multi-value Relative Distinguished Names correctly. Attackers could craft certificate subjects containing a single-value Relative Distinguished Name that would be interpreted as a multi-value Relative Distinguished Name, for example, in order to inject a Common Name that would allow bypassing the certificate subject verification.

Affected versions of Node.js do not accept multi-value Relative Distinguished Names and are thus not vulnerable to such attacks themselves. However, third-party code that uses node's ambiguous presentation of certificate subjects may be vulnerable.

More details will be available at CVE-2021-44533 after publication.

Prototype pollution via console.table properties (Low)(CVE-2022-21824)

Due to the formatting logic of the console.table() function it was not safe to allow user controlled input to be passed to the properties parameter while simultaneously passing a plain object with at least one property as the first parameter, which could be __proto__. The prototype pollution has very limited control, in that it only allows an empty string to be assigned numerical keys of the object prototype.

Versions of Node.js with the fix for this use a null protoype for the object these properties are being assigned to.

More details will be available at CVE-2022-21824 after publication.

Thanks to Patrik Oldsberg (rugvip) for reporting this vulnerability.

The module was initially introduced in Node.js v15.1.0 and is backported to v14.17.0 to enable testing it at a larger scale.

With diagnostics_channel, Node.js core and module authors can publish contextual data about what they are doing at a given time. This could be the hostname and query string of a mysql query, for example. Just create a named channel with dc.channel(name) and call channel.publish(data) to send the data to any listeners to that channel.

const dc = require('diagnostics_channel');
const channel = dc.channel('mysql.query');

MySQL.prototype.query = function query(queryString, values, callback) {
  // Broadcast query information whenever a query is made
  channel.publish({
    query: queryString,
    host: this.hostname,
  });

  this.doQuery(queryString, values, callback);
};

Channels are like one big global event emitter but are split into separate objects to ensure they get the best performance. If nothing is listening to the channel, the publishing overhead should be as close to zero as possible. Consuming channel data is as easy as using channel.subscribe(listener) to run a function whenever a message is published to that channel.

const dc = require('diagnostics_channel');
const channel = dc.channel('mysql.query');

channel.subscribe(({ query, host }) => {
  console.log(`mysql query to ${host}: ${query}`);
});

The data captured can be used to provide context for what an app is doing at a given time. This can be used for things like augmenting tracing data, tracking network and filesystem activity, logging queries, and many other things. It's also a very useful data source for diagnostics tools to provide a clearer picture of exactly what the application is doing at a given point in the data they are presenting.

UUID support in the crypto module

The new crypto.randomUUID() method now allows to generate random RFC 4122 Version 4 UUID strings:

const { randomUUID } = require('crypto');

console.log(randomUUID());
// 'aa7c91a1-f8fc-4339-b9db-f93fc7233429'

Experimental support for AbortController and AbortSignal

Node.js 14.17.0 adds experimental partial support for AbortController and AbortSignal.

Both constructors can be enabled globally using the --experimental-abortcontroller flag.

Additionally, several Node.js APIs have been updated to support AbortSignal for cancellation. It is not mandatory to use the built-in constructors with them. Any spec-compliant third-party alternatives should be compatible.

AbortSignal support was added to the following methods:

  • child_process.exec
  • child_process.execFile
  • child_process.fork
  • child_process.spawn
  • dgram.createSocket
  • events.on
  • events.once
  • fs.readFile
  • fs.watch
  • fs.writeFile
  • http.request
  • https.request
  • http2Session.request
  • The promisified variants of setImmediate and setTimeout

v14.16.0

This is a security release.

Notable changes

Vulnerabilities fixed:

  • CVE-2021-22883: HTTP2 'unknownProtocol' cause Denial of Service by resource exhaustion
    • Affected Node.js versions are vulnerable to denial of service attacks when too many connection attempts with an 'unknownProtocol' are established. This leads to a leak of file descriptors. If a file descriptor limit is configured on the system, then the server is unable to accept new connections and prevent the process also from opening, e.g. a file. If no file descriptor limit is configured, then this lead to an excessive memory usage and cause the system to run out of memory.
  • CVE-2021-22884: DNS rebinding in --inspect
    • Affected Node.js versions are vulnerable to denial of service attacks when the whitelist includes “localhost6”. When “localhost6” is not present in /etc/hosts, it is just an ordinary domain that is resolved via DNS, i.e., over network. If the attacker controls the victim's DNS server or can spoof its responses, the DNS rebinding protection can be bypassed by using the “localhost6” domain. As long as the attacker uses the “localhost6” domain, they can still apply the attack described in CVE-2018-7160.
  • CVE-2021-23840: OpenSSL - Integer overflow in CipherUpdate
