Pre-authentication flaws bypass access controls entirely, allowing attackers to execute code or extract data without any valid credentials or session tokens.

Most bot protection fails because it treats all automation as hostile, blocking legitimate tools while malicious scripts slip through behavioral gaps.

Website defacement is rarely a standalone theft attempt; it is a signal that an attacker has bypassed your perimeter and controls your server environment.

Input validation fails when teams treat it as a front-end feature rather than a backend constraint, leaving the core logic exposed to malformed data.

CAPTCHA creates friction that blocks automated abuse but simultaneously pushes attackers toward more expensive manual labor or sophisticated bot networks.

CSRF exploits the browser’s automatic inclusion of credentials, turning trusted sessions into attack vectors that standard access controls often miss.

HTTP request smuggling exploits parsing differences between proxies and backend servers, allowing attackers to hijack other users' sessions or bypass security controls without exploiting code bugs.

Defacement is often the visible tip of a larger compromise where the attacker already controls your server processes and database connections.
