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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N","score":7.4},"cwes":["CWE-346","CWE-863"],"references":["https://github.com/AsyncHttpClient/async-http-client/commit/d3bb4d68b41acf5d3ab7541afa9fdfe7ec3ba054","https://github.com/AsyncHttpClient/async-http-client/releases/tag/async-http-client-project-3.0.14","https://github.com/AsyncHttpClient/async-http-client/security/advisories/GHSA-v2j5-22fr-j62r"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:58:01.639778232+00:00"},"epss":{"cve":"CVE-2026-107230","score":0.00188,"percentile":0.08367,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-v2j5-22fr-j62r","url":"https://osv.dev/vulnerability/GHSA-v2j5-22fr-j62r","summary":"AsyncHttpClient: Pooled connections can still be shared across NTLM, Negotiate and proxy logins","modified":"2026-10-08T17:01:03.329024369Z","packages":[{"ecosystem":"Maven","name":"org.asynchttpclient:async-http-client","purl":"pkg:maven/org.asynchttpclient/async-http-client","ranges":[">=3.0.0 <3.0.14"],"fixed":["3.0.14"]},{"ecosystem":"Maven","name":"org.asynchttpclient:async-http-client","purl":"pkg:maven/org.asynchttpclient/async-http-client","ranges":[">=2.0.0 <=2.16.1"],"fixed":[]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
