5 Fundamental Cookie Vulnerabilities

Every major browser is moving away from cookies — here's why

Cookies are stored in SQLite databases with minimal encryption. Any process with filesystem access can read them.

Impact: Malware, backups, or physical access = stolen sessions

Stolen cookies can be replayed to impersonate users indefinitely. No device binding or location verification.

Impact: Full account takeover from anywhere in the world

Without HttpOnly flag, JS reads cookies via document.cookie. One XSS exploit = all sessions stolen.

Impact: Single injection point steals every active session

Without SameSite protection, cookies are sent automatically with cross-origin requests.

Impact: Unwanted actions executed silently as the victim

Without Secure flag, cookies travel in plaintext over HTTP. Public WiFi captures sessions trivially.

Impact: Man-in-the-middle interception on any network
