AI-suggested

Since the vulnerability affects versions prior to 6.4.1, upgrading to Tornado version 6.4.1 or later is implied as the remediation. Users should verify the vendor advisory for official patch availability and apply the update accordingly. Until patched, avoid using untrusted input in HTTP headers passed to CurlAsyncHTTPClient.

Description

Tornado's CurlAsyncHTTPClient class is vulnerable to HTTP request/response splitting due to improper neutralization of CRLF sequences in HTTP headers. This vulnerability allows attackers to inject arbitrary headers or additional HTTP requests when untrusted header values are used. It affects Tornado versions prior to 6.4.1 and has a medium severity rating.
