CVE-2026-35489
A unit ID from a different Space can be associated cross-space, leaking foreign-key references across tenant boundaries.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.22%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
Tandoor Recipes is an application for managing recipes, planning meals, and building shopping lists. Prior to 2.6.4, the POST /api/food/{id}/shopping/ endpoint reads amount and unit directly from request.data and passes them without validation to ShoppingListEntry.objects.create(). Invalid amount values (non-numeric strings) cause an unhandled exception and HTTP 500. A unit ID from a different Space can be associated cross-space, leaking foreign-key references across tenant boundaries. All other endpoints creating ShoppingListEntry use ShoppingListEntrySerializer, which validates and sanitizes these fields. This vulnerability is fixed in 2.6.4.
