Kerentanan Improper Neutralization of CRLF Sequences in HTTP Headers ('HTTP Request/Response Splitting') pada neoteroi blacksheep. Skor CVSS 3.1 5.3 (Medium) menurut NVD.

Deskripsi (NVD)

BlackSheep is an asynchronous web framework to build event based web applications with Python. Prior to 2.4.6, the HTTP Client implementation in BlackSheep is vulnerable to CRLF injection. Missing headers validation makes it possible for an attacker to modify the HTTP requests (e.g. insert a new header) or even create a new HTTP request. Exploitation requires developers to pass unsanitized user input directly into headers.The server part is not affected because BlackSheep delegates to an underlying ASGI server handling of response headers. This vulnerability is fixed in 2.4.6.
