DescriptionTandoor Recipes is an application for managing recipes, planning meals, and building shopping lists. Prior to 2.6.10, recipe utility endpoints retrieve same-Space Recipe objects without invoking the private-recipe owner or sharing permission when an authenticated member of a shared Space supplies another member's private recipe identifier to AI import, file, external-link, or share-link endpoints. Request processing uses api/ai-import/, api/get_recipe_file/, api/get_external_file_link/, api/share-link/, CustomRecipePermission. The attack works because the endpoints read private recipe files, send file bytes to the configured AI provider, or create and disclose external links without object-level authorization, and api/share-link/ can create a public link when Space sharing is enabled. This can expose private recipe files and sensitive uploaded content to another same-Space user and to configured external services. This issue is fixed in version 2.6.10.
