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.
