Thers is a xss issue in plugins/stats page of Admin Web UI.

Open Solr Admin Web UI, select a core(such as collection1) and then click "Plugins/stats",and type a url like "http://127.0.0.1:8983/solr/#/collection1/plugins/cache?entry=score=<img src=1 onerror=alert(1);> to the browser address, you will get alert box with "1".

I changed follow code to resolve this problem:
The Original code:
for( var i = 0; i < entry_count; i++ )

{ $( 'a[data-bean="' + entries[i] + '"]', frame_element ) .parent().addClass( 'expanded' ); }

The Changed code:
for( var i = 0; i < entry_count; i++ )

{ $( 'a[data-bean="' + entries[i].esc() + '"]', frame_element ) .parent().addClass( 'expanded' ); }
