Cookie dan sesi for SolidJS

high5 checks

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

What SolidJS 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

SolidJS context

Fine-grained reactive UI library compiling to direct DOM operations.

innerHTML prop is the escape hatch; treat it as a sink and sanitise input.
