Incorrect Behavior Order: Early Amplification

This flaw creates a significant security and performance risk by putting the cart before the horse. An attacker can exploit this by repeatedly requesting expensive operations—like complex calculations, large file generations, or database-intensive queries—without ever logging in. This can lead to immediate denial-of-service (DoS) conditions, exhausting server CPU, memory, or bandwidth, all while hiding behind the anonymity of an unauthenticated session. To prevent this, developers must enforce a strict order of operations: always authenticate the user and authorize the specific action first. The resource-heavy task should only execute after these security checks pass. Implementing rate-limiting on preliminary requests and placing expensive operations behind proper permission gates are critical mitigation strategies to stop this early amplification of cost before it cripples your system.
