Apache Software Foundation reports:

The Apache HTTPD web server (from 2.4.18-2.4.20) did not validate a X509
client certificate correctly when experimental module for the HTTP/2
protocol is used to access a resource.
The net result is that a resource that should require a valid client
certificate in order to get access can be accessed without that credential.
