Executive Summary

This vulnerability exists because the WebSocket Application Programming Interface does not limit the number of authentication requests that can be made.

Without restrictions on authentication attempts, an attacker can repeatedly try to authenticate, potentially overwhelming the system or attempting to guess credentials.

Impact Analysis

The lack of rate limiting on authentication requests can allow attackers to perform denial-of-service (DoS) attacks, which can disrupt service availability.

Additionally, attackers may conduct brute-force attacks to gain unauthorized access by repeatedly trying different authentication credentials.
