Cookie dan sesi for Spring Boot
high5 checks
Session cookies are the keys to an account. Missing attributes turn a single XSS bug into full account takeover.
What Spring Boot 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
- 1Set cookie attributes at the framework level so every cookie inherits them
- 2Move tokens out of localStorage to HttpOnly cookies
Spring Boot context
Java application framework with auto-configuration and embedded servers.
Actuator endpoints leak heap dumps and environment variables when exposed; restrict /actuator.
