{"cve":"CVE-2026-107282","nvd":{"published":"2026-10-07T22:17:04.167","modified":"2026-10-10T03:17:06.900","status":"Awaiting Analysis","description":"The AsyncHttpClient (AHC) library allows Java applications to easily execute HTTP requests and asynchronously process HTTP responses. Prior to 3.0.13  and 2.16.1, cross-host request replay updates the current request but leaves the target request and related proxy context pointing at the original origin. Connection-pool selection, CONNECT handling, realm selection, and TLS setup can consequently send the original host's path, Host header, Authorization credentials, or plaintext request to the replay destination. Documented ResponseFilter failover and retry paths can trigger the replay. This issue is fixed in versions 3.0.13 and 2.16.1.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:H/AT:P/PR:N/UI:N/VC:H/VI:H/VA:N/SC:H/SI:H/SA:N","score":9.4},"cvss_v3":null,"cwes":["CWE-319","CWE-441","CWE-522"],"references":["https://github.com/AsyncHttpClient/async-http-client/commit/15b254514a411623e5f1d8c99ea79c0f82f8a466","https://github.com/AsyncHttpClient/async-http-client/commit/bbc31aed3b044f9f7a126cf689a8c8d7ad2ae1cb","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","https://github.com/AsyncHttpClient/async-http-client/security/advisories/GHSA-jmqq-x5g9-9p2w"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:58:01.639778232+00:00"},"epss":{"cve":"CVE-2026-107282","score":0.00189,"percentile":0.08427,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-jmqq-x5g9-9p2w","url":"https://osv.dev/vulnerability/GHSA-jmqq-x5g9-9p2w","summary":"AsyncHttpClient: Replay to a different host sends the original host request and credentials to the new host","modified":"2026-10-08T16:45:19.474250752Z","packages":[{"ecosystem":"Maven","name":"org.asynchttpclient:async-http-client","purl":"pkg:maven/org.asynchttpclient/async-http-client","ranges":[">=3.0.0 <3.0.13"],"fixed":["3.0.13"]},{"ecosystem":"Maven","name":"org.asynchttpclient:async-http-client","purl":"pkg:maven/org.asynchttpclient/async-http-client","ranges":[">=2.0.0 <2.16.1"],"fixed":["2.16.1"]}]}],"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).
