The AsyncHttpClient (AHC) library allows Java applications to easily execute HTTP requests and asynchronously process HTTP responses. Prior to 3.0.13 and 2.16.1, cross-host request replay updates the current request but leaves the target request and related proxy context pointing at the original origin. Connection-pool selection, CONNECT handling, realm selection, and TLS setup can consequently send the original host's path, Host header, Authorization credentials, or plaintext request to the replay destination. Documented ResponseFilter failover and retry paths can trigger the replay. This issue is fixed in versions 3.0.13 and 2.16.1.
