 ------------------------------------------

# CVSS Score: 8.1 (High)

------------------------------------------
 Attack Type

 * Remote (Authenticated)
   
------------------------------------------

------------------------------------------
Vulnerability Details

* The application does not enforce proper rate limiting on the One-Time Password (OTP) verification endpoint. This allows an attacker to automate and brute-force OTP codes without restriction. By sending a high volume of OTP guesses in rapid succession, an attacker can potentially bypass the OTP verification mechanism of the mobile number.
