What is CVE-2026-35488?

CVE-2026-35488 is a high-severity missing authorization vulnerability in TandoorRecipes recipes, published on 7 Apr 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 2.6.4, RecipeBookViewSet and RecipeBookEntryViewSet use CustomIsShared as an alternative permission class, but CustomIsShared.has_object_permission() returns True for all HTTP methods — including DELETE, PUT, and PATCH — without checking request.method in SAFE_METHODS. Any user who is in the shared list of a RecipeBook can delete or overwrite it, even though shared access is semantically read-only. This vulnerability is fixed in 2.6.4.

Weakness: CWE-749
