## Description

A vulnerability in danny-avila/librechat version git a1647d7 allows an unauthenticated attacker to cause a denial of service by sending a crafted payload to the server. The middleware `checkBan` is not surrounded by a try-catch block, and an unhandled exception will cause the server to crash. This issue is fixed in version 0.7.6.

## What to do

- Check your stack: if you ship or depend on danny-avila danny-avila/librechat, upgrade to a fixed version (0.7.6) per the references below.
