Description

Tandoor Recipes is an application for managing recipes, planning meals, and building shopping lists. In versions prior to 2.6.0, the `SyncViewSet.query_synced_folder()` action in `cookbook/views/api.py` (line 903) fetches a Sync object using `get_object_or_404(Sync, pk=pk)` without including `space=request.space` in the filter. This allows an admin user in Space A to trigger sync operations (Dropbox/Nextcloud/Local import) on Sync configurations belonging to Space B, and view the resulting sync logs. Version 2.6.0 patches the issue.
