Prior to 3.0.13  and 2.16.1, ThreadSafeCookieStore validates Domain attributes with domain matching but does not reject public suffixes. A host beneath a suffix such as co.uk can set a cookie for that suffix, after which the shared cookie store sends it to unrelated hosts under the suffix. This can inject or overwrite session-relevant cookie values across origins. This issue is fixed in versions 3.0.13 and 2.16.1.","state":0,"publishedAt":"2026-10-07T21:15:13.87+00:00","modifiedAt":"2026-10-08T17:57:38.975+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, < 3.0.13\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 2.0.0, < 2.16.1\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:H/AT:P/PR:N/UI:N/VC:N/VI:N/VA:N/SC:N/SI:H/SA:N","score":6.9,"severity":"MEDIUM"}],"references":["https://github.com/AsyncHttpClient/async-http-client/security/advisories/GHSA-f9m8-cv68-674w","https://github.com/AsyncHttpClient/async-http-client/commit/330267895fe0bdb41bbd027ea6b151d38ee7c23d","https://github.com/AsyncHttpClient/async-http-client/commit/d1f0ccec417092098d40242fee7dfac84bb3c21f","https://github.com/AsyncHttpClient/async-http-client/releases/tag/async-http-client-project-2.16.1","https://github.com/AsyncHttpClient/async-http-client/releases/tag/async-http-client-project-3.0.13"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-107280","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-107280","identifiers":["CVE-2026-107280"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
