Echo: async-http-client, org.asynchttpclient:async-http-client: security update to 2.16.1

medium Tenable Cloud Security Plugin ID 457248

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - The AsyncHttpClient (AHC) library allows Java applications to easily execute HTTP requests and
 asynchronously process HTTP responses. From 2.14.5 to 2.16.0 and from 3.0.9 to 3.0.11, a client configured
 with a client-wide Realm and redirect following can disclose credentials after a cross-origin redirect
 because the Interceptors authentication path falls back to the client configuration after redirect
 handling clears the per-exchange realm. If the attacker-controlled target returns 401, the client can send
 Basic or Digest credentials or a Negotiate or NTLM token to that origin. Per-request realms are stripped
 correctly, and this issue is a residual bypass of the earlier cross-origin credential-stripping fixes.
 This issue is fixed in versions 2.16.1 and 3.0.12. (CVE-2026-85717)

Solution

Update the async-http-client library and its related packages to version 2.16.1 or later.
