  "title": "Cross-host replay state confusion in AsyncHttpClient",
  "summary": "AsyncHttpClient versions through 3.0.12 on the 3.x line and through 2.16.0 on the 2.x line can retain incorrect origin state when replaying a request to another host. Applications using cross-host ResponseFilter failover or retries may send request content, authorization data, or traffic lacking the expected TLS handling to the replay destination.",
  "mitigation": "Upgrade to AsyncHttpClient 3.0.13 or later on the 3.x line, or 2.16.1 or later on the 2.x line. Until upgraded, avoid cross-host ResponseFilter replays and disable retries where credentials or proxies are in use.",
