# CVE-2026-61726: Tandoor Recipes: Private recipe authorization bypass via /api/step/ - read and modify another Space member's private recipe content

- Also known as: GHSA-WJF3-FQ5W-7J7W
- Severity: CVSS 8.1 (High), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N
- CISA SSVC: exploitation=poc, automatable=no, technicalImpact=total

## Affected

- TandoorRecipes recipes: fixed in 2.6.12

## Description

Tandoor Recipes is an application for managing recipes, planning meals, and building shopping lists. Prior to 2.6.12, StepViewSet and IngredientViewSet filter only by active Space and use role-level CustomIsUser checks instead of the private-recipe owner or sharing predicate when an authenticated user with read and write API scope in the victim's Space supplies a private recipe or step identifier to the Step API. Request processing uses StepViewSet, IngredientViewSet, api/step/, api/step/{step_id}/, CustomIsUser, CustomRecipePermission. The attack works because the sub-resource querysets return and update private-recipe steps for non-owners because Space membership is accepted without recipe-level authorization. This can read and silently modify another same-Space member's private recipe instructions, while cross-Space access remains out of scope. This issue is fixed in version 2.6.12.

## What to do
