CVE-2026-107285

MediumCVSS 5.9/10Last modified Oct 8, 2026

Description

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'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.
