CVE-2026-107279 AsyncHttpClient: Digest mutual authentication is switched off by a peer offering qop=auth-int

The AsyncHttpClient AHC library allows Java applications to easily execute HTTP requests and asynchronously process HTTP responses. In 3.0.12, a peer offering only Digest qop=auth-int causes mutual-authentication verification to be skipped. AuthenticatorUtils.computeExpectedRspAuth returns no...
