{"id":"CVE-2026-107285","published":"2026-10-07T22:17:04.637","lastModified":"2026-10-08T20:35:31.200","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.","cvssScore":5.9,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N","cwes":["CWE-319","CWE-522"],"vendors":[],"products":[],"references":[{"url":"https://github.com/AsyncHttpClient/async-http-client/commit/6e9cb75a9b7259353f983fc90ca28b1da3742e18","tags":[]},{"url":"https://github.com/AsyncHttpClient/async-http-client/commit/c4feab0f7f86d61505a48e40d383c8a375a22e18","tags":[]},{"url":"https://github.com/AsyncHttpClient/async-http-client/releases/tag/async-http-client-project-2.16.1","tags":[]},{"url":"https://github.com/AsyncHttpClient/async-http-client/releases/tag/async-http-client-project-3.0.12","tags":[]},{"url":"https://github.com/AsyncHttpClient/async-http-client/security/advisories/GHSA-3wp9-xfwm-rjjf","tags":[]}],"exploitRefs":[{"url":"https://github.com/AsyncHttpClient/async-http-client/commit/6e9cb75a9b7259353f983fc90ca28b1da3742e18","tags":[]},{"url":"https://github.com/AsyncHttpClient/async-http-client/commit/c4feab0f7f86d61505a48e40d383c8a375a22e18","tags":[]},{"url":"https://github.com/AsyncHttpClient/async-http-client/releases/tag/async-http-client-project-2.16.1","tags":[]},{"url":"https://github.com/AsyncHttpClient/async-http-client/releases/tag/async-http-client-project-3.0.12","tags":[]},{"url":"https://github.com/AsyncHttpClient/async-http-client/security/advisories/GHSA-3wp9-xfwm-rjjf","tags":[]}],"hasPoc":true,"ai":null}
