cross-site scripting  
vulnerability because it fails to sufficiently sanitize user-supplied data.  
  
An attacker may leverage this issue to execute arbitrary script code in the  
browser of an unsuspecting user in the context of the affected site. This  
may allow the attacker to steal cookie-based authentication credentials and  
to launch other attacks.

The XSS reflected because the "impress_s" value is not filter correcly  
and it is possible bypassing the  
  
sanitize_text_field() wordpress function:  
  
<input type="text" id="impress_search_feed_input" name="impress_s"  
value="<?php echo (isset($_GET['impress_s']) &&  
!empty($_GET['impress_s'])) ? sanitize_text_field($_GET['impress_s'])  
: ""; ?>" required="required" />  
  
  
Demo url:*http://localhost/wordpress/wp-admin/admin.php?impress_s=  
<http://localhost/wordpress/wp-admin/admin.php?impress_s=>"  
onmouseover=alert(1)  
display=&page=imkt_feed&impress_search_btn=impress_search_feed_btn*
