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.
