The application handles secrets via environment variables, which is a good practice. Database interactions using SQLAlchemy's `text()` method with parameterized queries are correctly implemented to prevent SQL injection. Webhook endpoint `/webhook` is exposed, typical for such applications. The `WhatsAppClient` communicates with an external WhatsApp API, requiring trust in that external service. Some `docker-compose.base.yml` configurations use default credentials (`admin:admin` for WhatsApp API basic auth, `user:password` for Postgres) which are primarily for local development and are intended to be overridden by `.env` files in production/deployment, but could be a minor risk if deployed without proper `.env` configuration. `eval` or similar dangerous functions were not found.
