Tandoor Recipes's Unauthenticated Debug Parameter Leaks Full Raw SQL Queries Including Schema, Table Names, and Access Control Logic

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.
