[Security] Bump esbuild, vitest and @vitejs/plugin-react

Bumps esbuild to 0.25.3 and updates ancestor dependencies esbuild, vitest and @vitejs/plugin-react. These dependencies need to be updated together.

Updates esbuild from 0.21.5 to 0.25.3 This update includes a security fix.

Vulnerabilities fixed

esbuild enables any website to send any requests to the development server and read the response

Summary

esbuild allows any websites to send any request to the development server and read the response due to default CORS settings.

Details

esbuild sets Access-Control-Allow-Origin: * header to all requests, including the SSE connection, which allows any websites to send any request to the development server and read the response.

Attack scenario:

  1. The attacker serves a malicious web page (http://malicious.example.com).
  2. The user accesses the malicious web page.
  3. The attacker sends a fetch('http://127.0.0.1:8000/main.js') request by JS in that malicious web page. This request is normally blocked by same-origin policy, but that's not the case for the reasons above.
  4. The attacker gets the content of http://127.0.0.1:8000/main.js.

In this scenario, I assumed that the attacker knows the URL of the bundle output file name. But the attacker can also get that information by

v0.25.3

  • Fix lowered async arrow functions before super() (#4141, #4142)

    This change makes it possible to call an async arrow function in a constructor before calling super() when targeting environments without async support, as long as the function body doesn't reference this. Here's an example (notice the change from this to null):

    // Original code
    class Foo extends Object {
      constructor() {
        (async () => await foo())()
        super()
      }
    }
    // Old output (with --target=es2016)
    class Foo extends Object {
    constructor() {
    (() => __async(this, null, function* () {
    return yield foo();
    }))();
    super();
    }
    }
    // New output (with --target=es2016)
    class Foo extends Object {
    constructor() {
    (() => __async(null, null, function* () {
    return yield foo();
    }))();
    super();
    }
    }

    Some background: Arrow functions with the async keyword are transformed into generator functions for older language targets such as --target=es2016. Since arrow functions capture this, the generated code forwards this into the body of the generator function. However, JavaScript class syntax forbids using this in a constructor before calling super(), and this forwarding was problematic since previously happened even when the function body doesn't use this. Starting with this release, esbuild will now only forward this if it's used within the function body.

    This fix was contributed by @​magic-akari.

  • Fix memory leak with --watch=true (#4131, #4132)

    This release fixes a memory leak with esbuild when --watch=true is used instead of --watch. Previously using --watch=true caused esbuild to continue to use more and more memory for every rebuild, but --watch=true should now behave like --watch and not leak memory.

    This bug happened because esbuild disables the garbage collector when it's not run as a long-lived process for extra speed, but esbuild's checks for which arguments cause esbuild to be a long-lived process weren't updated for the new --watch=true style of boolean command-line flags. This has been an issue since this boolean flag syntax was added in version 0.14.24 in 2022. These checks are unfortunately separate from the regular argument parser because of how esbuild's internals are organized (the command-line interface is exposed as a separate Go API so you can build your own custom esbuild CLI).

    This fix was contributed by @​mxschmitt.

  • More concise output for repeated legal comments (#4139)

    Some libraries have many files and also use the same legal comment text in all files. Previously esbuild would copy each legal comment to the output file. Starting with this release, legal comments duplicated across separate files will now be grouped in the output file by unique comment content.

Changelog: 2024

This changelog documents all esbuild versions published in the year 2024 (versions 0.19.12 through 0.24.2).

0.24.2

  • Fix regression with --define and import.meta (#4010, #4012, #4013)

    The previous change in version 0.24.1 to use a more expression-like parser for define values to allow quoted property names introduced a regression that removed the ability to use --define:import.meta=.... Even though import is normally a keyword that can't be used as an identifier, ES modules special-case the import.meta expression to behave like an identifier anyway. This change fixes the regression.

    This fix was contributed by @​sapphi-red.

0.24.1

  • Allow es2024 as a target in tsconfig.json (#4004)

    TypeScript recently added es2024 as a compilation target, so esbuild now supports this in the target field of tsconfig.json files, such as in the following configuration file:

    {
      "compilerOptions": {
        "target": "ES2024"
      }
    }

    As a reminder, the only thing that esbuild uses this field for is determining whether or not to use legacy TypeScript behavior for class fields. You can read more in the documentation.

    This fix was contributed by @​billyjanitsch.

  • Allow automatic semicolon insertion after get/set

    This change fixes a grammar bug in the parser that incorrectly treated the following code as a syntax error:

    class Foo {
      get
      *x() {}
      set
      *y() {}
    }

    The above code will be considered valid starting with this release. This change to esbuild follows a similar change to TypeScript which will allow this syntax starting with TypeScript 5.7.

  • Allow quoted property names in --define and --pure (#4008)

    The define and pure API options now accept identifier expressions containing quoted property names. Previously all identifiers in the identifier expression had to be bare identifiers. This change now makes --define and --pure consistent with --global-name, which already supported quoted property names. For example, the following is now possible:

Updates @vitejs/plugin-react from 4.3.1 to 4.4.1

Release notes

Sourced from @​vitejs/plugin-react's releases.

plugin-react@4.4.1

Fix type issue when using moduleResolution: "node" in tsconfig #462

plugin-react@4.4.0

Make compatible with rolldown-vite

This plugin is now compatible with rolldown-powered version of Vite. Note that currently the __source property value position might be incorrect. This will be fixed in the near future.

plugin-react@4.4.0-beta.2

Add reactRefreshHost option

Add reactRefreshHost option to set a React Fast Refresh runtime URL prefix. This is useful in a module federation context to enable HMR by specifying the host application URL in the Vite config of a remote application. See full discussion here: module-federation/vite#183

export default defineConfig({
  plugins: [react({ reactRefreshHost: 'http://localhost:3000' })],
})

plugin-react@4.4.0-beta.1

No release notes provided.

plugin-react@4.3.4

Add Vite 6 to peerDependencies range

Vite 6 is highly backward compatible, not much to add!

Force Babel to output spec compliant import attributes #386

The default was an old spec (with type: "json"). We now enforce spec compliant (with { type: "json" })

plugin-react@4.3.3

React Compiler runtimeModule option removed

React Compiler was updated to accept a target option and runtimeModule was removed. vite-plugin-react will still detect runtimeModule for backwards compatibility.

When using a custom runtimeModule or target !== '19', the plugin will not try to pre-optimize react/compiler-runtime dependency.

The react-compiler-runtime is now available on npm can be used instead of the local shim for people using the compiler with React < 19.

Here is the configuration to use the compiler with React 18 and correct source maps in development:

npm install babel-plugin-react-compiler react-compiler-runtime @babel/plugin-transform-react-jsx-development
