Pull request overview
Updates the project’s tooling dependency tree to remediate GHSA-p9ff-h696-f583 by ensuring Vite is resolved to the patched version (7.3.2), even when previously only pulled in transitively via Vitest.
Changes:
- Add
vite@^7.3.2as an explicitdevDependencyto force the patched version. - Update
pnpm-lock.yamlto resolve all Vite references from7.3.1to7.3.2(including Vitest-related snapshots).

Vite 7.3.1 allows arbitrary file reads via the dev server WebSocket:
server.fsrestrictions were not enforced on thefetchModulehandler exposed viavite:invoke, enabling unauthenticated callers to retrieve any file as a JS module string.Changes
package.json: Addedviteas an explicitdevDependencyat^7.3.2(was previously only a transitive dep viavitest)pnpm-lock.yaml: Updated allvite@7.3.1references to7.3.2with the correct integrity hashReachability Assessment
Not reachable — high confidence.
The exploit requires the Vite dev server to be network-exposed (
--host/server.host). In this repo:next dev), not Vite — there is novite.config.tsvitestfor unit testing, which does not expose an HTTP/WS server to the networkvitest.config.mtshas noserver.hostconfigurationThis update satisfies vulnerability scanners; the codebase was not actively exposed to this CVE.
Original prompt
This section details the Dependabot vulnerability alert you should resolve
<alert_title>Vite Vulnerable to Arbitrary File Read via Vite Dev Server WebSocket</alert_title>
<alert_description>### Summary
server.fscheck was not enforced to thefetchModulemethod that is exposed in Vite dev server's WebSocket.Impact
Only apps that match the following conditions are affected:
--hostorserver.hostconfig option)server.ws: falseArbitrary files on the server (development machine, CI environment, container, etc.) can be exposed.
Details
If it is possible to connect to the Vite dev server’s WebSocket without an
Originheader, an attacker can invokefetchModulevia the custom WebSocket eventvite:invokeand combinefile://...with?raw(or?inline) to retrieve the contents of arbitrary files on the server as a JavaScript string (e.g.,export default "...").The access control enforced in the HTTP request path (such as
server.fs.allow) is not applied to this WebSocket-based execution path.PoC
Start the dev server on the target
Example (used during validation with this repository):
pnpm -C playground/alias exec vite --host 0.0.0.0 --port 5173Confirm that access is blocked via the HTTP path (example: arbitrary file)
curl -i 'http://localhost:5173/@fs/etc/passwd?raw'Result:

403 Restricted(outside the allow list)Confirm that the same file can be retrieved via the WebSocket path
By connecting to the HMR WebSocket without an
Originheader and sending avite:invokerequest that callsfetchModulewith afile://...URL and?raw, the file contents are returned as a JavaScript module.high

<task_instructions>Resolve this alert by updating the affected package to a non-vulnerable version. Prefer the lowest non-vulnerable version (see the patched_version field above) over the latest to minimize breaking changes. Include a Reachability Assessment section in the PR description. Review the alert_description field to understand which APIs, features, or configurations are affected, then search the codebase for usage of those specific items. If the vulnerable code path is reachable, explain how (which files, APIs, or call sites use the affected functionality) and note that the codebase is actively exposed to this vulnerability. If the vulnerable code path is not reachable, explain why (e.g. the affected API is never called, the vulnerable configuration is not used) and note that the update is primarily to satisfy vulnerability scanners rather than to address an active risk. If the advisory is too vague to determine reachability (e.g. 'improper input validation' with no specific API named), state that reachability could not be determined and explain why. Include a confidence level in the reachability assessment (e.g. high confidence if the advisory names a specific API and you confirmed it is or is not called, low confidence if the usage is indirect and hard to trace). If no patched version is available, check the alert_description field for a Workarounds section — the advisory may describe configuration changes or usage patterns that mitigate the vulnerability without a version update. If a workaround is available, apply it and leave a code comment referencing the advisory identifier explaining it is a temporary mitigation. If neither a patch nor a workaround is available, explain in the PR description why the alert cannot be resolved automatically...
