Cookie & Session Security Scanner

Audit cookie flags, session management, and token security for your application.

Cookies are the primary mechanism for maintaining user sessions. Insecure cookie configuration can lead to session hijacking, cross-site attacks, and data leakage. Our scanner checks all cookies set by your application for proper security flags and session management best practices.

What This Scanner Does

Analyzes all cookies set by your application for Secure, HttpOnly, SameSite flags, path restrictions, and expiration settings. Checks session token entropy, identifies overly permissive cookie scopes, and tests for session fixation vectors.

Why It Matters

Insecure cookies are a direct path to session hijacking. Without the HttpOnly flag, JavaScript can steal session tokens via XSS. Without the Secure flag, cookies transmit over unencrypted connections. Without SameSite, cookies are vulnerable to CSRF attacks.

Common Findings

  • Session cookie missing HttpOnly flag
  • Sensitive cookies sent without Secure flag
  • SameSite attribute not set on authentication cookies
  • Excessive cookie expiration times
