CVE-2026-35489Public exploitNetwork attack vector

Cross-tenant association and request crashes via unvalidated fields

Published Apr 7, 2026 · Updated Apr 7, 2026

Input validation flaws in Tandoor Recipes before 2.6.4 allow remote authenticated users to crash requests or create cross-space links. The POST /api/food/{id}/shopping/ handler passes amount and unit from request data directly to ShoppingListEntry.objects.create(), bypassing decimal and tenant-scope validation. Access to the endpoint and a valid food object are required; malformed amounts trigger HTTP 500 responses, while a foreign Space unit ID creates an unauthorized cross-tenant association.
