Summary

Tandoor Recipes before 2.6.10 is affected. Recipe utility endpoints return private recipes to any authenticated member of a shared Space who supplies another member's recipe identifier, because owner and sharing permissions are not checked. This authorization bypass (CWE-639) lets that user read private recipe files, send them to the configured AI provider, or create external links, exposing sensitive uploaded content.

Description from the CNA

Tandoor 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.
