Librechat: >> Librechat >> 0.0.5 Security Vulnerabilities
In danny-avila/librechat version git 0c2a583, there is an improper input validation vulnerability. The application uses multer middleware for handling multipart file uploads. When using in-memory storage (the default setting for multer), there is no limit on the upload file size. This can lead to a server crash due to out-of-memory errors when handling large files. An attacker without any privileges can exploit this vulnerability to cause a complete denial of service. The issue is fixed in version 0.7.6.

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.

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.
