Name of the Vulnerable Software and Affected Versions
AsyncHttpClient versions prior to 3.0.13
AsyncHttpClient versions prior to 2.16.1
Description
Cross-host request replay occurs when the current request is updated but the target request and related proxy context continue to point to the original origin. This can lead to the transmission of the original host's path, Host header, Authorization credentials, or plaintext requests to the replay destination during connection-pool selection, CONNECT handling, realm selection, and TLS setup. This behavior can be triggered by documented ResponseFilter failover and retry paths.
Recommendations
Update to version 3.0.13 or later.
Update to version 2.16.1 or later.
