wide variety of actions, such as stealing Administrators' session  
tokens, or performing arbitrary actions on their behalf. In order to  
exploit this issue, the attacker has to lure/force a logged on WordPress  
Administrator into opening a malicious website.

This issue exists in the file gad-admin-options-ui.php and is caused due to the lack of output encoding on the ga_email option/request parameter.  
  
<tr valign="top">  
<th scope="row">  
<label for="ga_email"><?php _e( 'Google Analytics Email', 'google-analytics-dashboard' ); ?></label></th>  
<td>  
<input name="ga_email" type="text" size="15" id="ga_email" class="regular-text" value="<?php echo isset( $_POST['ga_email'] ) ? $_POST['ga_email'] : get_option( 'gad_login_email' ); ?>" />  
</td>  
</tr>  
  
In order to exploit this issue, the attacker has to lure/force a logged on WordPress Administrator into opening a malicious website.
