8.0.3→8.0.5GitHub Vulnerability Alerts
GHSA-4w7w-66w2-5vf9
Summary
Any files ending with
.mapeven out side the project can be returned to the browser.Impact
Only apps that match the following conditions are affected:
--hostorserver.hostconfig option).mapand the path is predictableDetails
In Vite v7.3.1, the dev server’s handling of
.maprequests for optimized dependencies resolves file paths and callsreadFilewithout restricting../segments in the URL. As a result, it is possible to bypass theserver.fs.strictallow list and retrieve.mapfiles located outside the project root, provided they can be parsed as valid source map JSON.PoC
/@​fsaccess is blocked bystrict(returns 403)../segments under the optimized deps.mapURL prefix to reach/tmp/poc.mapCVE-2026-39363
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.GHSA-v2wj-q39q-566r
Summary
The contents of files that are specified by
server.fs.denycan be returned to the browser.Impact
Only apps that match the following conditions are affected:
--hostorserver.hostconfig option)server.fs.allowserver.fs.denyDetails
On the Vite dev server, files that should be blocked by
server.fs.deny(e.g.,.env,*.crt) can be retrieved with HTTP 200 responses when query parameters such as?raw,?import&raw, or?import&url&inlineare appended.PoC
pnpm exec vite root --host 127.0.0.1 --port 5175 --strictPortserver.fs.denyis enforced (expect 403):curl -i http://127.0.0.1:5175/src/.env | head -n 20Release Notes
