Impact

Due to missing canonicalization when readDir is called recursively, it was possible to display directory listings outside of the defined fs scope. This required a crafted symbolic link or junction folder inside an allowed path of the fs scope. No arbitrary file content could be leaked.

Patches

The issue has been resolved in #5123 and the implementation now properly checks if the
requested (sub) directory is a symbolic link outside of the defined scope.

Workarounds

Disable the readDir endpoint in the allowlist inside the tauri.conf.json.
