Summary
Vite's `server.fs.deny` did not deny requests for patterns with directories.
Details

Summary

Vite dev server option server.fs.deny did not deny requests for patterns with directories. An example of such a pattern is /foo/**/*.

Impact

Only 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) are affected.

Patches

Fixed 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

Details

server.fs.deny uses picomatch with the config of { matchBase: true }. matchBase 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 unless they are explicitly defined.

Reproduction

Set fs.deny to ['**/.git/**'] and then curl for /.git/config.

  • with matchBase: true, you can get any file under .git/ (config, HEAD, etc).
  • with matchBase: false, you cannot get any file under .git/ (config, HEAD, etc).
