Exposure of Sensitive Information to an Unauthorized Actor
TL;DR
When routing HTTPS requests through a proxy, the client keys proxy connections by the proxy address and reuses a completed CONNECT tunnel for later requests to a different destination origin. A request intended for one origin is therefore sent inside the TLS stream established to a previously contacted origin. The earlier origin can observe requests, headers, credentials, and bodies meant for a different destination. The fix reconnects the proxy tunnel when the destination origin changes and binds the tunneled TLS handshake to the destination hostname.
How do I fix this?
Upgrade the aiosonic library to the patch version.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range and you send HTTPS requests to more than one destination origin through the same HTTPS proxy.
