Sidebar-Link plugin file upload blocked by CSRF protection

When on the /configure page when trying to upload a new image to /userContent using the sidebar-link plugin the following error is generated.

HTTP ERROR 403
Problem accessing /plugin/sidebar-link/upload. Reason:
No valid crumb was included in the request
Powered by Jetty:// 9.4.z-SNAPSHOT

The result of this error is due to CSRF protection in Jenkins 2.x.  The current workaround is for a user to complete the following steps:

• Visit /configureSecurity page
• Disable Prevent Cross Site Request Forgery exploits ** temporarily
• Visit /configure upload the image desired
