CORS Misconfiguration: How to Prevent It
A too-generous CORS policy can let a malicious site read authenticated responses from your API. Reflecting the Origin with credentials is the classic mistake.
JWT Security Vulnerabilities and How to Avoid Them

Mass Assignment Vulnerability: How to Prevent It
Mass assignment lets attackers set fields you never meant to expose — like isAdmin or accountBalance — by adding them to a request body. Here is the fix.
FastAPI Security Best Practices: A 2026 Guide
