A serious flaw occurs when OTP validation is performed on the client side instead of the server side. This allows attackers to intercept, modify, or bypass OTP verification, leading to unauthorized access and loss of system integrity.
To prevent this, OTP verification should always occur on the server side, where the logic and secrets are securely stored. Client-side validation should only handle input submission, while the server must verify authenticity, enforce expiration, and invalidate the OTP after a single use.
