SCA: security update for org.asynchttpclient:async-http-client (GHSA-fmxf-pm6p-7xgm)

high Tenable Cloud Security Plugin ID 442064

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. Versions on the 2.x branch prior to 2.15.0 and the 3.x branch prior
 to 3.0.10 leak `Cookie` headers to cross-origin redirect targets. When following a redirect to a different
 origin, the `propagatedHeaders()` method in `Redirect30xInterceptor.java` strips `Authorization` and
 `Proxy-Authorization` headers but does not strip the `Cookie` header, causing session cookies and other
 sensitive cookie values to be sent to attacker-controlled servers. Versions 2.15.0 and 3.0.10 patch the
 issue. (CVE-2026-45300)

Solution

Update the org.asynchttpclient:async-http-client library and its related packages to version 2.15.0 or later.
