Improper Input Validation in LibreChat by Danny Avila

CVE-2024-11171

What is CVE-2024-11171?

The vulnerability in LibreChat arises from improper input validation related to multipart file uploads handled by the multer middleware. When configured with in-memory storage, which is the default, there is no restriction on the size of files that can be uploaded. This oversight can be exploited by an attacker to upload excessively large files, potentially leading to out-of-memory errors and resulting in a denial of service. Users are encouraged to upgrade to version 0.7.6, which addresses this significant issue.
