If you cannot patch yet, restrict access to trusted users and monitor for unauthorized access attempts related to category data.
Description
KitchenOwl versions up to 0.7.10 have an authorization bypass vulnerability where the application does not verify that category IDs belong to the authenticated user's household. This allows authenticated users to enumerate and access category details such as names, budgets, and colors from other households, breaking household data isolation.
