Cookie dan sesi for PHP
high5 checks
Session cookies are the keys to an account. Missing attributes turn a single XSS bug into full account takeover.
What PHP 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
PHP context
Server-side scripting runtime used by most CMS and many custom apps.
Runtime CVEs are pre-auth and application-independent (PHP2Shell CVE-2026-109618/109619). Keep PHP on a supported, patched branch.
