Vitest: Path Traversal / Arbitrary File Read via @​vitest/mocker Redirect Mock

CVE-2026-84373 / GHSA-82fw-gwwq-j7x9

More information

Details

Summary

@vitest/mocker registers a redirect mock's target path without validating it
against the dev server's file-serving allowlist. An attacker who can reach the
dev server's WebSocket can register a redirect mock pointing outside the project
root; when the mocked module is requested, the plugin's load hook returns
readFile(<attacker path>) as the module source, disclosing local files.

This is exploitable without authentication only through the public
mockerPlugin / standalone interceptorPlugin exports (used by third-party dev
servers), which register the handler on Vite's unauthenticated HMR socket.
Vitest's own browser mode registers mocks over a token-authenticated RPC and
is not remotely reachable by default (see Scope).

Affected code

packages/mocker/src/node/interceptorPlugin.ts.

The load hook is the file-read sink:

if (mock.type === 'redirect') {
  return readFile(mock.redirect, 'utf-8')
}

mock.redirect is derived from client input at registration time with no
boundary check:

if (event.type === 'redirect') {
  const redirectUrl = new URL(event.redirect)
  event.redirect = join(server.config.root, redirectUrl.pathname)
}
registry.register(event)

There is no server.fs.allow / server.fs.deny check and no assertion that the
resolved path stays within the project root.

Registration paths and trust boundaries

• Public mockerPlugin / interceptorPlugin (unauthenticated). In
  configureServer, the plugin registers server.ws.on('vitest:interceptor:register', …)
  on Vite's HMR WebSocket. That socket performs no token, Origin, or same-origin
  check, so any client that can reach it can register a redirect mock. This is
  the path the "unauthenticated" impact applies to.
• Vitest browser mode (authenticated). Mocks register over the browser RPC
  (registerMock), which sits behind a per-run token (isValidApiRequest, a
  random api.token). The interceptor's configureServer socket is not used for
  registration here (in v5 it does not run at all, as the plugin is injected per
  environment). The same missing boundary check exists on the authenticated RPC
  path, but reaching it requires the token, so it is not a remote-unauthenticated
  read.

Path handling

new URL(redirect).pathname combined with join(root, pathname) does not
confine reads to the root:

• Special/hierarchical schemes (file:, http:) are normalized by WHATWG URL,
  so .. segments are collapsed and the result stays under the root. Payloads of
  the form file:///../../etc/passwd do not escape.
• A non-special (opaque) scheme preserves .. in pathname, so
  join(root, "../../…/etc/passwd") resolves outside the root and reads an
  arbitrary file.

Even without escaping the root, the missing server.fs check allows reading any
in-root file the dev server would otherwise refuse to serve (for example an
in-root .env or source that is denied by server.fs.deny).

Scope / preconditions

• This is a development-server issue. The dev server binds to localhost by
  default and is not reachable from the network unless the developer exposes it
  (server.host / 0.0.0.0, a LAN bind, or a proxy).
• A raw (non-browser) client against a reachable server bypasses browser origin
  and CORS protections entirely and can both register the mock and read the
  response.
• A browser-based drive-by against a localhost server is substantially mitigated
  by Vite defaults: the default CORS origin allowlist is limited to localhost
  origins, and server.allowedHosts blocks DNS-rebinding, so a cross-origin page
  cannot read the file contents back.

Impact

Disclosure of local files readable by the dev-server process (source, in-root
.env/secrets, and, via the opaque-scheme payload, files outside the project
root). No integrity or availability impact.

Affected versions

Present since @vitest/mocker was introduced.

• Affected: @vitest/mocker >= 2.1.0 (shipped in vitest and
  @vitest/browser >= 2.1.0), through 4.1.x and the 5.0.0 pre-releases.
• Fixed: Vitest 4.1.11 and 5.0.0. Older majors (2.1.x, 3.x) are not
  maintained and are not planned to receive the fix.

Fix

Validate the resolved redirect target against Vite's file-serving allowlist
(isFileLoadingAllowed) before registering it, at every registration site, and
stop registering the interceptor WebSocket events in Vitest's browser mode
(mocks there flow through the authenticated RPC).

Merge Risk: 🔵 Low · up to d41f1

The Nix unit check still uses Vitest 3.2.7, so it will not validate this upgrade. Regenerate its dependency source before relying on that check; the issue is limited to test confidence.

official Bun documentation bun run package executable shebang interpreter

💡 Result:

The official Bun docs say that `bun run` can execute package executables and respects their shebangs by default. For example, a CLI with `#!/usr/bin/env node` runs using Node; add `--bun` to run it with Bun instead: `bun run --bun vite`. ([bun.sh](https://bun.sh/docs/runtime?utm_source=openai))

For `bunx`, the equivalent is `bunx --bun my-cli`; without `--bun`, a `node` shebang launches Node. ([bun.sh](https://bun.sh/docs/pm/bunx?utm_source=openai))

NixOS nixpkgs typescript package propagatedBuildInputs nodejs package expression

💡 Result:

Current nixpkgs defines TypeScript at [`pkgs/by-name/ty/typescript/package.nix`](https://github.com/NixOS/nixpkgs/blob/master/pkgs/by-name/ty/typescript/package.nix). It uses `buildNpmPackage` and does **not** declare `propagatedBuildInputs` or `nodejs` directly—the npm builder supplies the Node.js build environment. ([github.com](https://github.com/NixOS/nixpkgs/blob/master/pkgs/by-name/ty/typescript/package.nix?utm_source=openai))

If you’re writing your own package and want Node.js available to dependents, the expression could look like:

```nix
{ stdenv, nodejs }:

stdenv.mkDerivation {
  pname = "my-typescript-tool";
  version = "1.0.0";

  propagatedBuildInputs = [ nodejs ];
}
```

That propagation makes Node.js available to packages that depend on yours; it isn’t how nixpkgs packages TypeScript itself. ([github.com](https://github.com/NixOS/nixpkgs/blob/master/doc/stdenv/stdenv.chapter.md?utm_source=openai))

Run Vitest 5 with Node.js

test-web-unit invokes Vitest through Bun, but Bun follows Vitest's #!/usr/bin/env node shebang. The Nix unit-test environment does not put node on PATH, so Vitest can fail before tests run. Add a supported pkgs.nodejs to the unit-test inputs, or retain a compatible Vitest version.

Regenerate the Nix dependency source for Vitest 4.1.11.

The Nix web check uses pkgs/id/web/bun.nix, which still contains Vitest 3.2.7 entries. The current pkgs/id/web/bun.lock selects Vitest 4.1.11, and the reachable check has no separate install step that supplies the Vitest 4 packages. The offline check can therefore fail during dependency installation or avoid exercising the upgraded Vitest suite.

Run just bun2nix to regenerate pkgs/id/web/bun.nix.
