Tandoor Recipes: Cross-user IDOR in /api/recipe-from-source/ bookmarklet import — read and destroy another space member's pending BookmarkletImport

Overview

Tandoor Recipes is an application for managing recipes, planning meals, and building shopping lists. Prior to 2.6.10, looks up BookmarkletImport by sequential primary key within the active Space without restricting created_by to the requesting user when an authenticated member of a shared Space submits another member's pending bookmarklet identifier to POST /api/recipe-from-source/. Request processing uses api/recipe-from-source/, BookmarkletImport, filter, delete. The attack works because the endpoint parses and returns the victim's stored URL and captured page content, then unconditionally deletes the victim's pending import. This can disclose authenticated or private captured page content and destroy another Space member's pending import. This issue is fixed in version 2.6.10.
