This high-severity CVE scores 7.4 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.2% (7th percentile of EPSS-scored CVEs). GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

A fix is available — apply it.

The AsyncHttpClient (AHC) library allows Java applications to easily execute HTTP requests and asynchronously process HTTP responses. From 2.0.0 until 3.0.14, connection-pool partitioning still omits identity-defining fields for Kerberos, SPNEGO, NTLM, and authenticated proxy connections. Logins without a configured principal, proxy realms, identities sharing a user name, and SOCKS or CONNECT proxy logins can reuse a socket authenticated as a different identity. A later request is then executed under the first identity and can expose that identity's data or authority to another caller. In the affected execution path, SpnegoEngine, NTLM, Kerberos, SPNEGO, SOCKS, and CONNECT control or expose the vulnerable behavior. This issue is fixed in version 3.0.14.
