Cookie dan sesi for Payload

high5 checks

Session cookies are the keys to an account. Missing attributes turn a single XSS bug into full account takeover.

What Payload must have

  • Secure attribute on every cookie
  • HttpOnly on session cookies
  • SameSite=Lax or Strict on session cookies
  • No session identifier in URLs or localStorage
  • Session rotation after login and logout invalidation

How to fix it

  1. 1Set cookie attributes at the framework level so every cookie inherits them
  2. 2Move tokens out of localStorage to HttpOnly cookies

Payload context

TypeScript headless CMS with an admin panel on Next.js.

Access control functions decide per-collection permissions; defaults are often too open.
