CVE-2026-101033
Authenticated attackers can enumerate category IDs from other households to read their category names, budgets, and colors, breaking household isolation.
Does this matter?
Lower severity and a low EPSS score (0.22%). Track it; it rarely justifies an emergency change on its own.
Description
KitchenOwl through 0.7.10 fails to verify that category IDs belong to the caller's household in expense and item operations. Authenticated attackers can enumerate category IDs from other households to read their category names, budgets, and colors, breaking household isolation.
