How to fix?

There is no fixed version for express-brute.

Overview

express-brute is a brute-force protection middleware for express routes that rate-limits incoming requests, increasing the delay with each request in a fibonacci-like sequence.

Affected versions of this package are vulnerable to Rate Limiting Bypass due to incorrectly counting the number of requests sent, this allows an attacker to bypass the rate-limiting mechanism.
