{"cve":"CVE-2026-107285","nvd":{"published":"2026-10-07T22:17:04.637","modified":"2026-10-08T20:35:31.200","status":"Awaiting Analysis","description":"The AsyncHttpClient (AHC) library allows Java applications to easily execute HTTP requests and asynchronously process HTTP responses. Prior to 3.0.12 and 2.16.1, a proxied ws request is carried through CONNECT, but NettyRequestFactory.newNettyRequest and requestUri decide whether to attach proxy authentication and an absolute-form target only from whether the URI is secure. Because ws is not marked secure, the tunneled WebSocket upgrade sent to the origin includes the proxy's Proxy-Authorization value. Basic credentials are directly recoverable and Digest responses can be replayed or cracked offline. This issue is fixed in versions 3.0.12 and 2.16.1.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N","score":5.9},"cwes":["CWE-319","CWE-522"],"references":["https://github.com/AsyncHttpClient/async-http-client/commit/6e9cb75a9b7259353f983fc90ca28b1da3742e18","https://github.com/AsyncHttpClient/async-http-client/commit/c4feab0f7f86d61505a48e40d383c8a375a22e18","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-3.0.12","https://github.com/AsyncHttpClient/async-http-client/security/advisories/GHSA-3wp9-xfwm-rjjf"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:58:01.639778232+00:00"},"epss":{"cve":"CVE-2026-107285","score":0.00206,"percentile":0.10512,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-3wp9-xfwm-rjjf","url":"https://osv.dev/vulnerability/GHSA-3wp9-xfwm-rjjf","summary":"AsyncHttpClient: WebSocket proxy credentials sent to the origin server over a CONNECT tunnel","modified":"2026-10-08T16:45:18.877610661Z","packages":[{"ecosystem":"Maven","name":"org.asynchttpclient:async-http-client","purl":"pkg:maven/org.asynchttpclient/async-http-client","ranges":[">=3.0.0 <3.0.12"],"fixed":["3.0.12"]},{"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).
