## Security Alert: Production App Uses Insecure Cookie-Based Auth, Risking Authentication Bypass
A critical security vulnerability has been exposed in a production application's authentication system. The current implementation relies on a basic, insecure cookie-based mechanism, directly violating the project's stated "Security by Design" principle. This flaw creates a high-risk pathway for attackers to bypass authentication entirely, posing a severe threat to system integrity and user data.

The system's authentication is fundamentally broken. It stores credentials in environment variables, lacks any session management or CSRF (Cross-Site Request Forgery) protection, and is explicitly vulnerable to cookie manipulation attacks. This combination of weaknesses makes the application's login gate effectively porous. The required fix is a complete architectural overhaul: migrating from the flawed cookie system to a robust NextAuth.js framework.

Implementation demands are extensive and non-negotiable for security. The plan includes integrating NextAuth.js with secure session management, adding CSRF protection, and supporting multiple authentication providers. Crucially, sessions must be stored in a database using a Prisma adapter—not in cookies—with proper expiration controls. Further enhancements mandate proper JWT handling, secure cookie configuration, and rate limiting on all authentication endpoints to lock down the attack surface.
