CVE-2026-107232

Description

The AsyncHttpClient (AHC) library allows Java applications to easily execute HTTP requests and asynchronously process HTTP responses. Prior to 3.0.12 on 3.x and 2.16.1 on 2.x, the client infers that an HTTP proxy tunnel exists from the last request method rather than the CONNECT result. After a proxy rejects CONNECT, redirect or authentication handlers can write an origin request and its Authorization credentials onto the still-plaintext proxy connection. Basic credentials can be recovered directly, while NTLM responses may be cracked or relayed. This issue is fixed in versions 3.0.12 and 2.16.1.
