## What is CVE-2026-61726?

CVE-2026-61726 is a high-severity missing authorization vulnerability in TandoorRecipes recipes, published on 16 Oct 2026. Any signed-in user can exploit it over the network, with no action from the victim.

### Official 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.

Weakness: CWE-863 (Incorrect Authorization), CWE-639 (Authorization Bypass Through User-Controlled Key), CWE-284 (Improper Access Control)
