Apache HttpClient vulnerabilities

Apache HttpClient versions prior to version 4.5.13 and 5.0.3 can misinterpret malformed authority component in request URIs passed to the library as java.net.URI object and pick the wrong target host for request execution.

In Apache HttpClient versions 4.3.x before 4.3.1, it does not ensure that X509HostnameVerifier is not null, which may allow attackers to exploit vulnerabilities involving hostname verification.

In Apache HttpClient 5.6, a missing critical step in authentication allows an attacker to force the client to accept SCRAM-SHA-256 authentication without proper mutual authentication verification. The issue is fixed in version 5.6.1.
