tandoor CVE Vulnerabilities & Metrics

Tandoor Recipes is an application for managing recipes, planning meals, and building shopping lists. Prior to 2.6.5, a critical Denial of Service (DoS) vulnerability was in the recipe import functionality. This vulnerability allows an authenticated user to crash the server or make a significantly degrade its performance by uploading a large size ZIP file (ZIP Bomb). This vulnerability is fixed in 2.6.5.

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.

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.

Tandoor Recipes is an application for managing recipes, planning meals, and building shopping lists. Prior to 2.6.4, Tandoor Recipes allows authenticated users to inject arbitrary <style> tags into recipe step instructions. The bleach.clean() sanitizer explicitly whitelists the <style> tag, causing the backend to persist and serve unsanitized CSS payloads via the API. Any client consuming instructions_markdown from the API and rendering it as HTML without additional sanitization will execute attacker-controlled CSS — enabling UI redressing, phishing overlays, visual defacement, and CSS-based data exfiltration. This vulnerability is fixed in 2.6.4.

Tandoor Recipes is an application for managing recipes, planning meals, and building shopping lists. Prior to 2.6.4, the PUT /api/recipe/batch_update/ endpoint in Tandoor Recipes allows any authenticated user within a Space to modify any recipe in that Space, including recipes marked as private by other users. This bypasses all object-level authorization checks enforced on standard single-recipe endpoints (PUT /api/recipe/{id}/), enabling forced exposure of private recipes, unauthorized self-grant of access via the shared list, and metadata tampering. This vulnerability is fixed in 2.6.4.

Tandoor Recipes is an application for managing recipes, planning meals, and building shopping lists. In versions prior to 2.6.0, the Recipe API endpoint exposes a hidden `?debug=true` query parameter that returns the complete raw SQL query being executed, including all table names, column names, JOIN relationships, WHERE conditions (revealing access control logic), and multi-tenant space IDs. This parameter works even when Django's `DEBUG=False` (production mode) and is accessible to any authenticated user regardless of their privilege level. This allows a low-privilege attacker to map the entire database schema and reverse-engineer the authorization model. Version 2.6.0 patches the issue.

Tandoor Recipes is an application for managing recipes, planning meals, and building shopping lists. In versions prior to 2.6.0, Tandoor Recipes configures Django REST Framework with BasicAuthentication as one of the default authentication backends. The AllAuth rate limiting configuration (ACCOUNT_RATE_LIMITS: login: 5/m/ip) only applies to the HTML-based login endpoint at /accounts/login/. Any API endpoint that accepts authenticated requests can be targeted via Authorization: Basic headers with zero rate limiting, zero account lockout, and unlimited attempts. An attacker can perform high-speed password guessing against any known username. Version 2.6.0 patches the issue.

Tandoor Recipes is an application for managing recipes, planning meals, and building shopping lists. In versions prior to 2.6.0, the FDC (USDA FoodData Central) search endpoint constructs an upstream API URL by directly interpolating the user-supplied `query` parameter into the URL string without URL-encoding. An attacker can inject additional URL parameters by including `&` characters in the query value. This allows overriding the API key, manipulating upstream query behavior, and causing server crashes (HTTP 500) via malformed requests — a Denial of Service condition. Version 2.6.0 patches the issue.

Tandoor Recipes is an application for managing recipes, planning meals, and building shopping lists. In versions prior to 2.6.0, the image processing pipeline in Tandoor Recipes explicitly skips EXIF metadata stripping, image rescaling, and size validation for WebP and GIF image formats. A developer TODO comment in the source code acknowledges this as a known issue. As a result, when users upload recipe photos in WebP format (the default format for modern smartphone cameras), their sensitive EXIF data — including GPS coordinates, camera model, timestamps, and software information — is stored and served to all users who can view the recipe. Version 2.6.0 fixes the issue.

Tandoor Recipes is an application for managing recipes, planning meals, and building shopping lists. In versions prior to 2.6.0, the `SyncViewSet.query_synced_folder()` action in `cookbook/views/api.py` (line 903) fetches a Sync object using `get_object_or_404(Sync, pk=pk)` without including `space=request.space` in the filter. This allows an admin user in Space A to trigger sync operations (Dropbox/Nextcloud/Local import) on Sync configurations belonging to Space B, and view the resulting sync logs. Version 2.6.0 patches the issue.

Tandoor Recipes is an application for managing recipes, planning meals, and building shopping lists. Prior to 2.5.1, there is a Blind Server-Side Request Forgery (SSRF) vulnerability in the Cookmate recipe import feature of Tandoor Recipes. The application fails to validate the destination URL after following HTTP redirects, allowing any authenticated user (including standard users without administrative privileges) to force the server to connect to arbitrary internal or external resources. The vulnerability lies in cookbook/integration/cookmate.py, within the Cookmate integration class. This vulnerability can be leveraged to scan internal network ports, access cloud instance metadata (e.g., AWS/GCP Metadata Service), or disclose the server's real IP address. This vulnerability is fixed in 2.5.1.

Tandoor Recipes is an application for managing recipes, planning meals, and building shopping lists. Prior to 2.5.1, a Path Traversal vulnerability in the RecipeImport workflow of Tandoor Recipes allows authenticated users with import permissions to read arbitrary files on the server. This vulnerability stems from a lack of input validation in the file_path parameter and insufficient checks in the Local storage backend, enabling an attacker to bypass storage directory restrictions and access sensitive system files (e.g., /etc/passwd) or application configuration files (e.g., settings.py), potentially leading to full system compromise. This vulnerability is fixed in 2.5.1.

Tandoor Recipes 2.0.0-alpha-1, fixed in 2.0.0-alpha-2, is vulnerable to privilege escalation. This is due to the rework of the API, which resulted in the User Profile API Endpoint containing two boolean values indicating whether a user is staff or administrative. Consequently, any user can escalate their privileges to the highest level.

Tandoor Recipes is an application for managing recipes, planning meals, and building shopping lists. The file upload feature allows to upload arbitrary files, including html and svg. Both can contain malicious content (XSS Payloads). This vulnerability is fixed in 1.5.28.

Tandoor Recipes is an application for managing recipes, planning meals, and building shopping lists. The external storage feature allows any user to enumerate the name and content of files on the server. This vulnerability is fixed in 1.5.28.

Tandoor Recipes is an application for managing recipes, planning meals, and building shopping lists. A Jinja2 SSTI vulnerability allows any user to execute commands on the server. In the case of the provided Docker Compose file as root. This vulnerability is fixed in 1.5.24.

Recipes version 1.5.10 allows arbitrary HTTP requests to be made through the server. This is possible because the application is vulnerable to SSRF.

In Recipes, versions 0.17.0 through 1.2.5 are vulnerable to Stored Cross-Site Scripting (XSS), in the ‘Name’ field of Keyword, Food and Unit components. When a victim accesses the Keyword/Food/Unit endpoints, the XSS payload will trigger. A low privileged attacker will have the victim's API key and can lead to admin's account takeover.

In Recipes, versions 1.0.5 through 1.2.5 are vulnerable to Stored Cross-Site Scripting (XSS), in copy to clipboard functionality. When a victim accesses the food list page, then adds a new Food with a malicious javascript payload in the ‘Name’ parameter and clicks on the clipboard icon, an XSS payload will trigger. A low privileged attacker will have the victim's API key and can lead to admin's account takeover.

In Recipes, versions 1.0.5 through 1.2.5 are vulnerable to Stored Cross-Site Scripting (XSS), in “Add to Cart” functionality. When a victim accesses the food list page, then adds a new Food with a malicious javascript payload in the ‘Name’ parameter and clicks on the Add to Shopping Cart icon, an XSS payload will trigger. A low privileged attacker will have the victim's API key and can lead to admin's account takeover.

In Recipes, versions 0.9.1 through 1.2.5 are vulnerable to Server Side Request Forgery (SSRF), in the “Import Recipe” functionality. When an attacker enters the localhost URL, a low privileged attacker can access/read the internal file system to access sensitive information.
