Kerentanan Improper Neutralization of CRLF Sequences ('CRLF Injection') pada aiohttp. Skor CVSS 3.1 7.5 (High) menurut NVD.

Deskripsi (NVD)

AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to 3.14.0, attacker-controlled input included into multipart/payload headers can be used to modify a request to inject additional headers or similar. In the unlikely situation that an application is passing user-controlled strings into MultipartWriter.append(headers=...) or Payload.headers, then an attacker may be able to modify the request to inject headers or change the contents of the request. This vulnerability is fixed in 3.14.0.
