Name of the Vulnerable Software and Affected Versions fastapi-proxy-lib version 0.0.1

Description The issue arises from the shared use of httpx.AsyncClient across different user clients, leading to the persistent storage of cookies based on the set-cookie response header. This results in a cookie leakage issue among all user clients sharing the same httpx.AsyncClient.

Recommendations For version 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. For the best solution, upgrade to version 0.1.0 or later.
