From 2.1.0 until 3.0.14, the enabled-by-default cookie store replaces a Cookie header explicitly supplied through setHeader or addHeader whenever the store contributes any cookie for the origin. In a shared client, stored cookies originating from one user can replace a different user's request cookie, causing the request to execute under the wrong session. This bypasses the earlier CVE-2024-53990 remediation, which covered cookies supplied through addCookie but not a directly supplied header. This issue is fixed in version 3.0.14.","state":0,"publishedAt":"2026-10-07T20:54:34.703+00:00","modifiedAt":"2026-10-08T16:08:44.837+00:00","affected":[{"ecosystem":"Vendor product","name":"async-http-client","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"AsyncHttpClient\",\n                    \"product\": \"async-http-client\",\n                    \"versions\": [\n                        {\n                            \"version\": \">= 3.0.0, < 3.0.14\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 2.1.0, <= 2.16.1\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:N","score":6.8,"severity":"MEDIUM"}],"references":["https://github.com/AsyncHttpClient/async-http-client/security/advisories/GHSA-2jwh-9rmr-j4xf","https://github.com/AsyncHttpClient/async-http-client/commit/fd9763620725126c1c8bb0af1ceb9a7523099a5f","https://github.com/AsyncHttpClient/async-http-client/releases/tag/async-http-client-project-3.0.14"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-107228","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-107228","identifiers":["CVE-2026-107228"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
