Doc Text:
A flaw was found in Tornado's `CurlAsyncHTTPClient` component. This vulnerability, known as CRLF (Carriage Return Line Feed) injection, occurs because the client fails to properly reject carriage return and line feed characters in HTTP request headers. A remote attacker can exploit this by injecting these characters into header values, allowing them to inject arbitrary headers or construct entirely new HTTP requests. This could potentially lead to server-side request forgery (SSRF) vulnerabilities.

Description OSIDB Bzimport 2026-09-15 15:46:22 UTC 
Tornado before 6.4.1 contains a CRLF injection vulnerability in CurlAsyncHTTPClient that fails to reject carriage return and line feed characters in request headers. Attackers can inject CRLF sequences into header values to inject arbitrary headers or construct entirely new HTTP requests.
