Plugin security / MonsterInsights

MonsterInsights vulnerability: is your WooCommerce store affected?

MonsterInsights has one serious security hole rated 7 or higher out of 10 that someone can use with no login or with only a customer account. The newest was published on 12 May 2026. Every one is fixed: update to 10.1.3 or newer.

Short answer: your store is affected if it runs MonsterInsights older than 10.1.3. Update to 10.1.3 or newer, on a copy of the store first if you can.

In our check of 3,600 live UK and US WooCommerce stores (31 October 2026 to 1 November 2026), 9 were running a version of MonsterInsights with a serious hole that already had a fix. How we checked.

How to check your version

  1. Log in to WordPress and open Plugins > Installed Plugins.
  2. Find MonsterInsights. The version number is under its name. If it is lower than 10.1.3, your store is affected.
  3. No login to hand? Open https://yourstore.com/wp-content/plugins/google-analytics-for-wordpress/readme.txt in a browser, with your own address in place of yourstore.com, and read the Stable tag line. Some hosts block this file; then use step 1.

How to fix it

  1. Make a backup, or better, a staging copy of the store (most hosts have a one-click staging button).
  2. On the copy, update MonsterInsights to 10.1.3 or newer: Dashboard > Updates, or Update now on the Plugins page.
  3. If no update shows, it may be a paid version whose licence has run out: download the new version from the seller's site and upload it.
  4. Place a test order on the copy: add to cart, check out, pay with a test method. Check the pages that use MonsterInsights.
  5. If everything works, make the same update on the live store and place one more test order.
  6. If you no longer use MonsterInsights, delete it instead of leaving it deactivated.

Questions

Which MonsterInsights version fixes it?
Version 10.1.3 or newer fixes the issue on this page.
How do I know if my store is affected?
Your store is affected if it runs MonsterInsights older than 10.1.3. In WordPress, open Plugins and read the version under MonsterInsights. Without logging in, open yourstore.com/wp-content/plugins/google-analytics-for-wordpress/readme.txt and read the Stable tag line.
I don't use MonsterInsights any more. Is a deactivated copy safe?
Deactivating it lowers the risk but leaves the old code on your server. If you don't use it, delete it; if you do, update it.
Can someone fix it for me?
Yes. We update the store on a copy first, place a test order, and only then make the same change on the live store, for a fixed price.
