Vite Server Options (server.fs.deny) can be bypassed using double forward-slash (//) allows any unauthenticated user to read file from the Vite root-path of the application including the default fs.deny settings (['.env', '.env.*', '*.{crt,pem}'])
Impact
Only users explicitly exposing the Vite dev server to the network (using --host or server.host config option) are affected, and only files in the immediate Vite project root folder could be exposed.
Patches
Fixed in vite@4.3.9, vite@4.2.3, vite@4.1.5, vite@4.0.5
And in the latest minors of the previous two majors: vite@3.2.7, vite@2.9.16
Details
Vite serve the application with under the root-path of the project while running on the dev mode. By default, vite using server options fs.deny to protected the sensitive information of the file. But, with simply double forward-slash, we can bypass this fs restriction.
PoC
Create a new latest project of vite using any package manager. (here I'm using react and vue templates for tested and pnpm)
Serve the application on dev mode using pnpm run dev.
Directly access the file from url using double forward-slash (//) (e.g: //.env, //.env.local)
Server Options fs.deny restrict successfully bypassed.
