Attributi di sicurezza dei cookie

Perché è importante

Cookies without the Secure, HttpOnly and SameSite flags can be sent over insecure connections, read by injected scripts or attached to cross-site requests. Session cookies are the most sensitive.

Come risolvere

1. Add Secure so the cookie is only sent over HTTPS.
2. Add HttpOnly to every cookie that JavaScript does not need to read.
3. Add SameSite=Lax (or Strict) to reduce cross-site request forgery.
