GHSA-28m8-9j7v-x499
No affected components available
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.
