From 2.1.0 until 3.0.14, the default ThreadSafeCookieStore does not retain whether a Set-Cookie response used a secure transport. It accepts Secure cookies received over plaintext and permits insecure cookies to overlay or delete existing Secure cookies with matching scope. An attacker controlling a plaintext same-site response can consequently plant, replace, or remove cookie state later sent to an HTTPS origin, enabling session fixation, CSRF-token replacement, or loss of security-relevant state. This issue is fixed in version 3.0.14.","state":0,"publishedAt":"2026-10-12T18:34:18.996+00:00","modifiedAt":"2026-10-13T20:25:00.134+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\": \">= 2.1.0, <= 2.16.1\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 3.0.0, < 3.0.14\",\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:H/A:N","score":6.8,"severity":"MEDIUM"}],"references":["https://github.com/AsyncHttpClient/async-http-client/security/advisories/GHSA-p2jm-6hj6-9rjg","https://github.com/AsyncHttpClient/async-http-client/commit/6ec7ee45034d154f502852a962d2891746fb82c1","https://github.com/AsyncHttpClient/async-http-client/releases/tag/async-http-client-project-3.0.14"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-107226","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-107226","identifiers":["CVE-2026-107226"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
