CVE-2026-85717
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.
