A CVE ID has been requested and we’ll update this post when it is assigned.

Authenticated Stored XSS

In the main “lara-google-analytics.php” script, the lrgawidget_setProfileID action is used to call the lrgawidget_callback function via the WordPress AJAX API.

add_action( 'wp_ajax_lrgawidget_setProfileID', 'lrgawidget_callback' );
function lrgawidget_callback() {
   global $wpdb;
   $user_id = get_current_user_id();
   $lrperm = lrgawidget_internal_permissions();
   $lrdata = $_POST;
   $modifiedAction = explode("_", $lrdata['action']);
   $lrdata['action'] = $modifiedAction[1];

   if ($lrdata['action'] == "setProfileID"){
      if ( (isset($lrdata['enable_universal_tracking'])) && !empty($lrdata['property_id'])){
         update_option('lrgawidget_property_id', $lrdata['property_id']);

Attackers are using it to inject JS code in the property_id field. It is injected into all pages and posts of the CMS:

Note that the attack requires a user account on the blog, such as a subscriber.


The vulnerability was reported to the team on October 13, 2019, and a new version 2.0.5 was released the same day.


Update as soon as possible if you have version 2.0.4 or below installed.
Note that the new version was released only a few hours after we reported the issue – which is a great thing – and it does block the ongoing attack, however it still lacks capability check and hopefully the author will come up with a better patch in the next few days.
