  "title": "Vite's `server.fs.deny` did not deny requests for patterns with directories.",
  "summary": "### Summary\n[Vite dev server option](https://vitejs.dev/config/server-options.html#server-fs-deny) `server.fs.deny` did not deny requests for patterns with directories. An example of such a pattern is `/foo/**/*`.\n\n### Impact\nOnly apps setting a custom `server.fs.deny` that includes a pattern with directories, and explicitly exposing the Vite dev server to the network (using `--host` or [`server.host` config option](https://vitejs.dev/config/server-options.html#server-host)) are affected.\n\n### Patches\nFixed in vite@5.2.6, vite@5.1.7, vite@5.0.13, vite@4.5.3, vite@3.2.10, vite@2.9.18\n\n### Details\n`server.fs.deny` uses picomatch with the config of `{ matchBase: true }`. [matchBase](https://github.com/micromatch/picomatch/blob/master/README.md#options:~:text=Description-,basename,-boolean) only matches the basename of the file, not the path due to a bug (https://github.com/micromatch/picomatch/issues/89). The vite config docs read like you should be able to set fs.deny to glob with picomatch. Vite also does not set `{ dot: true }` and that causes [dotfiles not to be denied](https://github.com/micromatch/picomatch/blob/master/README.md#options:~:text=error%20is%20thrown.-,dot,-boolean) unless they are explicitly defined.\n\n**Reproduction**\n\nSet fs.deny to `['**/.git/**']` and then curl for `/.git/config`.\n\n* with `matchBase: true`, you can get any file under  `.git/` (config, HEAD, etc).\n* with `matchBase: false`, you cannot get any file under  `.git/` (config, HEAD, etc).\n",
