AI Analysis
Technical Summary
CVE-2026-101033 describes an authorization bypass in KitchenOwl through version 0.7.10. The application fails to verify ownership of category IDs in expense and item operations, enabling authenticated attackers to enumerate category IDs from other households and read sensitive category information. This breaks the intended household isolation model.
Potential Impact
Authenticated attackers can access category information belonging to other households, including category names, budgets, and colors. This leads to a breach of household data isolation, potentially exposing sensitive financial categorization data to unauthorized users. The vulnerability does not require user interaction and has a low complexity of attack but requires authentication.
Mitigation Recommendations
