CVE-2024-51501 (opens in a new tab)How to fix?
Upgrade Refit to version 8.0.0 or higher.
Overview
Affected versions of this package are vulnerable to CRLF Injection due to header-related attributes: Header, HeaderCollection and Authorize, through the HttpHeaders.TryAddWithoutValidation method. An attacker can manipulate HTTP headers or perform HTTP request smuggling.
Notes:
This is not necessarily a security issue for a command line application, but if such code were present in a web application then it becomes vulnerable to request splitting.
This is a potential vulnerability in applications using Refit, not in Refit itself.
