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.","state":0,"publishedAt":"2026-10-07T21:28:34.62+00:00","modifiedAt":"2026-10-08T17:57:33.271+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, <3.0.12\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 2.0.0, < 2.16.1\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 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,"severity":"MEDIUM"}],"references":["https://github.com/AsyncHttpClient/async-http-client/security/advisories/GHSA-3wp9-xfwm-rjjf","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"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-107285","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-107285","identifiers":["CVE-2026-107285"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
