Kerentanan Allocation of Resources Without Limits or Throttling pada librechat. Skor CVSS 3.1 6.5 (Medium) menurut github.com.

Deskripsi (NVD)

LibreChat is an enhanced ChatGPT clone that supports multiple AI providers. Prior to 0.8.4-rc1, the fix for CVE-2024-11171 (commit bb58a2d0) added limits: { fileSize } to createMulterInstance() in the file upload routes. However, the POST /api/convos/import endpoint uses a separate multer instance that was never updated with the same limits configuration. Combined with the application-level size check being disabled by default (the CONVERSATION_IMPORT_MAX_FILE_SIZE_BYTES env var is commented out in .env.example), an authenticated user can upload arbitrarily large files to exhaust server disk space and memory. This vulnerability is fixed in 0.8.4-rc1.
