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."}, {"lang": "es", "value": "En la versi\u00f3n git 0c2a583 de danny-avila/librechat, existe una vulnerabilidad de validaci\u00f3n de entrada incorrecta.
