      <title>CVE-2026-107285 — AsyncHttpClient: WebSocket proxy credentials sent to the origin server over a CONNECT tunnel</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-107285</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; AsyncHttpClient async-http-client&lt;/p&gt;
&lt;p&gt;The AsyncHttpClient (AHC) library allows Java applications to easily execute HTTP requests and asynchronously process HTTP responses. Prior to 3.0.12 and 2.16.1, a proxied ws request is carried through CONNECT, but NettyRequestFactory.newNettyRequest and requestUri decide whether to attach proxy authentication and an absolute-form target only from whether the URI is secure. Because ws is not marked secure, the tunneled WebSocket upgrade sent to the origin includes the proxy&amp;#39;s Proxy-Authorization value. Basic credentials are directly recoverable and Digest responses can be replayed or cracked offline. This issue is fixed in versions 3.0.12 and 2.16.1.&lt;/p&gt;</description>
