{"cve":"CVE-2026-107226","nvd":{"published":"2026-10-12T19:16:37.880","modified":"2026-10-16T20:02:37.630","status":"Awaiting Analysis","description":"The AsyncHttpClient (AHC) library allows Java applications to easily execute HTTP requests and asynchronously process HTTP responses. 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.","cvss_v4":null,"cvss_v3":{"version":"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},"cwes":["CWE-384","CWE-693"],"references":["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","https://github.com/AsyncHttpClient/async-http-client/security/advisories/GHSA-p2jm-6hj6-9rjg"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:58:52.678897993+00:00"},"epss":{"cve":"CVE-2026-107226","score":0.00294,"percentile":0.2178,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-p2jm-6hj6-9rjg","url":"https://osv.dev/vulnerability/GHSA-p2jm-6hj6-9rjg","summary":"AsyncHttpClient: Cookies received over plaintext HTTP can plant, overwrite or delete Secure cookies set over HTTPS","modified":"2026-10-08T17:00:11.085978299Z","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":[">=2.1.0 <=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).
