Summary

Tandoor Recipes before 2.6.12 is affected. The Step API does not check recipe ownership or sharing and accepts any step identifier from the same Space (CWE-639). An authenticated user with read and write API scope can read and silently modify another Space member's private recipe instructions.

Description from the CNA

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.
