This repository is a local security lab baseline (demo data, intentional misconfigurations, and PCI-style anti-patterns for training). Do not deploy it to production or point it at real cardholder data.
If you believe you have found a security issue in this demo project itself, open a private advisory or contact the repository owner. This is not a production service and has no bug bounty.
Never commit .env files or database files. Use .env.example as a template and generate strong values locally for JWT_SECRET and SESSION_SECRET.
