NVD description
An unhandled exception in the danny-avila/librechat repository, version git 600d217, can cause the server to crash, leading to a full denial of service. This issue occurs when certain API endpoints receive malformed input, resulting in an uncaught exception. Although a valid JWT is required to exploit this vulnerability, LibreChat allows open registration, enabling unauthenticated attackers to create an account and perform the attack. The issue is fixed in version 0.7.6.
What to do
- Upgrade LibreChat to
0.7.6or later. - Do not expose the component's API or UI to the internet without authentication in front of it.
