CVE-2017-1000401

The Jenkins 2.73.1 and earlier, 2.83 and earlier default form control for
passwords and other secrets, <f:password/>, supports form validation (e.g.
for API keys). The form validation AJAX requests were sent via GET, which
could result in secrets being logged to a HTTP access log in non-default
configurations of Jenkins, and made available to users with access to these
log files. Form validation for <f:password/> is now always sent via POST,
which is typically not logged.
