Details

Tauri's readDir Endpoint Scope can be Bypassed With Symbolic Links ### 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 https://github.com/tauri-apps/tauri/pull/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`. ### For more information This issue was initially reported by [martin-ocasek]( https://github.com/martin-ocasek) in [#4882](https://github.com/tauri-apps/tauri/issues/4882).
