"title": "Vite dev server option `server.fs.deny` can be bypassed when hosted on case-insensitive filesystem",

"summary": "### Summary\n[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.\n\nThis bypass is similar to https://nvd.nist.gov/vuln/detail/CVE-2023-34092 -- with surface area reduced to hosts having case-insensitive filesystems.\n\n### Patches\nFixed in vite@5.0.12, vite@4.5.2, vite@3.2.8, vite@2.9.17\n\n### Details\nSince `picomatch` defaults to case-sensitive glob matching, but the file server doesn't discriminate; a blacklist bypass is possible. \n\nSee `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\n\nBy requesting raw filesystem paths using augmented casing, the matcher derived from `config.server.fs.deny` fails to block access to sensitive files. \n\n### PoC\n**Setup**\n1. Created vanilla Vite project using `npm create vite@latest` on a Standard Azure hosted Windows 10 instance. \n - `npm run dev -- --host 0.0.0.0`\n - Publicly accessible for the time being here: http://20.12.242.81:5173/ \n2. Created dummy secret files, e.g. `custom.secret` and `production.pem`\n3. Populated `vite.config.js` with\n```javascript\nexport default { server: { fs: { deny: ['.env', '.env.*', '*.{crt,pem}', 'custom.secret'] } } }\n```\n\n**Reproduction**\n1. `curl -s http://20.12.242.81:5173/@fs//`\n - Descriptive error page reveals absolute filesystem path to project root\n2. `curl -s http://20.12.242.81:5173/@fs/C:/Users/darbonzo/Desktop/vite-project/vite.config.js`\n - Discoverable configuration file reveals locations of secrets\n3. `curl -s http://20.12.242.81:5173/@fs/C:/Users/darbonzo/Desktop/vite-project/custom.sEcReT`\n - Secrets are directly accessible using case-augmented version of filename\n\n**Proof**\n\n\n### Impact\n**Who**\n- Users with exposed dev servers on environments with case-insensitive filesystems\n\n**What**\n- Files protected by `server.fs.deny` are both discoverable, and accessible",
