# Portfolio security review
This repository is a sanitized portfolio copy of a pre-production prototype.
Changes made before publication/share:
- removed the original SMTP configuration and password,
- removed the original SQLite database containing test reservations/contact data,
- removed `node_modules`,
- stopped serving the entire project directory as public static files,
- removed default `admin/admin` owner credentials,
- replaced browser-side storage of the owner password with a short-lived server session token,
- changed cancellation to require both order number and cancellation token,
- strengthened cancellation token generation,
- restricted simulated online payment endpoints behind `ENABLE_TEST_PAYMENTS=true`,
- made CORS opt-in rather than open by default.
Remaining pre-production limitations:
- no real online payment provider is connected,
- refund handling is an adapter stub,
- in-memory owner sessions disappear on server restart,
- rate limiting is minimal and in-memory,
- the availability check and reservation insert are not protected by a database-level exclusion/transaction strategy for high concurrency,
- customer and invoice data are stored in local SQLite without application-level encryption.
These limitations are intentionally documented rather than presented as production-ready behavior.
