Summary

CVE-2023-47641 is a security vulnerability affecting versions of the aioHTTP asynchronous HTTP library for Python. The issue lies in its inconsistent handling of the HTTP protocol when both Content-Length and Transfer-Encoding headers are present. This can result in incorrect interpretation of entities, allowing an attacker to bypass proxy rules and poison sockets with malicious data, including authentication headers or even Open Redirects. The impact of this vulnerability is significant, as it can lead to unauthorized access and data theft. Users are strongly advised to upgrade to version 3.8.0 of aioHTTP to mitigate this risk, as there are currently no known workarounds for this vulnerability.
