Official description

Tandoor Recipes is an application for managing recipes, planning meals, and building shopping lists. Prior to 2.6.4, RecipeBookViewSet and RecipeBookEntryViewSet use CustomIsShared as an alternative permission class, but CustomIsShared.has_object_permission() returns True for all HTTP methods — including DELETE, PUT, and PATCH — without checking request.method in SAFE_METHODS. Any user who is in the shared list of a RecipeBook can delete or overwrite it, even though shared access is semantically read-only. This vulnerability is fixed in 2.6.4.
