How to fix?

Upgrade org.asynchttpclient:async-http-client-project to version 2.0.35 or higher.


org.asynchttpclient:async-http-client-project is a package that allows Java applications to easily execute HTTP requests and asynchronously process the response.

Affected versions of this package are vulnerable to Server Side Request Forgery (SSRF). Async Http Client (aka async-http-client) before 2.0.35 can be tricked into connecting to a host different from the one extracted by if a '?' character occurs in a fragment identifier. Similar bugs were previously identified in cURL (CVE-2016-8624) and Oracle Java 8
