WPForms Lite vulnerability: is your WooCommerce store affected?

WPForms Lite has 2 serious security holes 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 28 May 2026. Every one is fixed: update to 1.10.0.5 or newer.

Short answer: your store is affected if it runs WPForms Lite older than 1.10.0.5. Update to 1.10.0.5 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), 25 were running a version of WPForms Lite 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 WPForms Lite. The version number is under its name. If it is lower than 1.10.0.5, your store is affected.
  3. No login to hand? Open https://yourstore.com/wp-content/plugins/wpforms-lite/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 WPForms Lite to 1.10.0.5 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 WPForms Lite.
  5. If everything works, make the same update on the live store and place one more test order.
  6. If you no longer use WPForms Lite, delete it instead of leaving it deactivated.

Questions

Which WPForms Lite version fixes it?
Version 1.10.0.5 or newer fixes all 2 issues on this page.
How do I know if my store is affected?
Your store is affected if it runs WPForms Lite older than 1.10.0.5. In WordPress, open Plugins and read the version under WPForms Lite. Without logging in, open yourstore.com/wp-content/plugins/wpforms-lite/readme.txt and read the Stable tag line.
I don't use WPForms Lite 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.
