Advisory

Affected versions of the lm-sys FastChat package are vulnerable to Denial of Service (DoS). The file upload feature fails to properly validate the length of filenames in multipart form-data requests, leading to server resource exhaustion. An unauthenticated attacker can exploit this vulnerability by sending a specially crafted HTTP request with an excessively large filename in the form-data boundary, resulting in the server becoming overwhelmed and unavailable to legitimate users.
