CVE-2026-23838

Tandoor Recipes is a recipe manager than can be installed with the Nix package manager. Starting in version 23.05 and prior to version 26.05, when using the default configuration of Tandoor Recipes, specifically using SQLite and default MEDIA_ROOT, the full database file may be externally accessible, potentially on the Internet. The root cause is that the NixOS module configures the working directory of Tandoor Recipes, as well as the value of MEDIA_ROOT, to be /var/lib/tandoor-recipes. This causes Tandoor Recipes to create its db.sqlite3 database file in the same directory as MEDIA_ROOT causing it to be accessible without authentication through HTTP like any other media file. This is the case when using GUNICORN_MEDIA=1 or when using a web server like nginx to serve media files. NixOS 26.05 changes the default value of MEDIA_ROOT to a sub folder of the data directory. This only applies to configurations with system.stateVersion >= 26.05. For older configurations, one of the workarounds should be applied instead. NixOS 25.11 has received a backport of this patch, though it doesn't fix this vulnerability without user intervention. A recommended workaround is to move MEDIA_ROOT into a subdirectory. Non-recommended workarounds include switching to PostgreSQL or disallowing access to db.sqlite3.
