Details

Summary

__screenshot-error handler on the browser mode HTTP server that responds any file on the file system. Especially if the server is exposed on the network by browser.api.host: true, an attacker can send a request to that handler from remote to get the content of arbitrary files.

Details

This __screenshot-error handler on the browser mode HTTP server responds any file on the file system. https://github.com/vitest-dev/vitest/blob/f17918a79969d27a415f70431e08a9445b051e45/packages/browser/src/node/plugin.ts#L88-L130

This code was added by https://github.com/vitest-dev/vitest/commit/2d62051f13b4b0939b2f7e94e88006d830dc4d1f.

PoC

  2. Run npx vitest init browser
  3. Run npm run test:browser
  4. Run curl http://localhost:63315/__screenshot-error?file=/path/to/any/file
