Summary

Cookie leakage between different users in fastapi-proxy-lib

Details

Impact

In the implementation of version 0.0.1, requests from different user clients are processed using a shared httpx.AsyncClient.

However, one oversight is that the httpx.AsyncClient will persistently store cookies based on the set-cookie response header sent by the target server and share these cookies across different user requests.

This results in a cookie leakage issue among all user clients sharing the same httpx.AsyncClient.

Patches

It's fixed in 0.1.0

Workarounds

If you insist 0.0.1: - Do not use ForwardHttpProxy at all. - Do not use ReverseHttpProxy or ReverseWebSocketProxy for any servers that may potentially send a set-cookie response.

However, it's best to upgrade to the latest version.
