NewCVE-2026-107282 (opens in a new tab)How to fix?
Upgrade org.asynchttpclient:async-http-client to version 2.16.1, 3.0.13 or higher.
Overview
org.asynchttpclient:async-http-client is a maven plugin for the Async Http Client (AHC) classes.
Affected versions of this package are vulnerable to Cleartext Transmission of Sensitive Information via the ResponseFilter failover and retry process. An attacker can intercept sensitive information, such as authorization credentials or plaintext requests, by triggering a replay to a different host, causing the original host's request data to be sent to the unintended destination.
Note: Replaying to the same host is not affected.
Workaround
Do not use a ResponseFilter that replays to a different host, and disable request retries, if the client is configured with credentials or used through a proxy.
