GHSA-8gvc-j273-4wm5: Path Traversal
First published: Tue Feb 04 2025(Updated: )
### 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`](https://vitest.dev/guide/browser/config.html#browser-api), 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 1. Create a directory and change the current directory to that directory 1. Run `npx vitest init browser` 1. Run `npm run test:browser` 2. Run `curl http://localhost:63315/__screenshot-error?file=/path/to/any/file` ### Impact Users explicitly exposing the browser mode server to the network by [`browser.api.host: true`](https://vitest.dev/guide/browser/config.html#browser-api) may get any files exposed.
