From 2.16.0 until 3.0.14, ThreadSafeCookieStore incompletely validates cookie Domain attributes. Missing private-section and default public-suffix rules, absent A-label normalization, locale-sensitive lowercasing, public-suffix host-only handling, and numeric or IP host checks allow one origin to store a cookie later sent to another origin. Applications sharing one client across trust domains can therefore receive attacker-injected cookies and may be exposed to session fixation. This issue is fixed in version 3.0.14.","state":0,"publishedAt":"2026-10-07T20:57:36.676+00:00","modifiedAt":"2026-10-08T17:57:44.807+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\": \">= 3.0.11, < 3.0.14\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 2.16.0, <= 2.16.1\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:N/I:L/A:N","score":4,"severity":"MEDIUM"}],"references":["https://github.com/AsyncHttpClient/async-http-client/security/advisories/GHSA-qjr7-w8pj-pmv9","https://github.com/AsyncHttpClient/async-http-client/commit/7dc5bbc2d0a48aa2a9caf089a626dcfd333168e9","https://github.com/AsyncHttpClient/async-http-client/releases/tag/async-http-client-project-3.0.14"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-107229","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-107229","identifiers":["CVE-2026-107229"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
