1. The Most Exploited E-Commerce Flaw: Insecure Direct Object References (IDOR)
IDOR vulnerabilities allow malicious actors to iterate through order IDs and dump customer invoices. Stilmerce strictly couples object lookups with authenticated user session context at the repository layer.
2. Distributed Sliding-Window Rate Limiting
Sliding-window Redis logs prevent burst-at-boundary exploits, throttling coupon guessing and credential stuffing attempts deterministically.
3. Hardened Security Headers with Helmet and Content Security Policy
Strict CSP rules, HSTS preloading, and Clickjacking frame restrictions eliminate client-side script injection vectors.
