Autentikasi dan sesi for Next.js
high5 checks
Authentication is the highest-value target on any site: credential stuffing, session fixation and CSRF all aim at the same door.
What Next.js must have
- Login forms post over HTTPS with a CSRF token
- Rate limiting and lockout on failed attempts
- MFA available for privileged accounts
- Passwords screened against known breach corpora
- No account enumeration through error messages
How to fix it
- 1Add per-account and per-IP throttling
- 2Enforce MFA for admins and screen passwords with a k-anonymity API
Next.js context
React framework with server-side rendering, routing and API routes, usually deployed on Vercel or Node.
Server components and middleware carry the auth boundary. Middleware-only auth was bypassable via CVE-2025-29927 — enforce authorisation in the route itself.
