Details

Cookie leakage between different users in fastapi-proxy-lib ### 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.** ### References fixed in [#10](https://github.com/WSH032/fastapi-proxy-lib/pull/10)
