Critical Vulnerability Detected in WooCommerce

A critical vulnerability concerning WooCommerce and the WooCommerce Blocks feature plugin was identified.

What actions should I take?

Automatic software updates are currently rolling out to all stores running impacted versions of each plugin – we still highly recommend you ensure that you’re using the latest versions of WooCommerce and WooCommerce Blocks (5.5.1).

To do this without causing issues, first update to the highest number possible in your release branch – this will ensure your website is no longer vulnerable.

For example: If your store is running WooCommerce 4.8, first update to WooCommerce 4.8.1 – the highest version number in that branch – before going ahead and updating to WooCommerce 5.5.1.

It’s always a good idea to keep up-to-date with the latest versions of WooCommerce.

Has any data been compromised?

Woocommerce investigation into this vulnerability and whether data has been compromised is ongoing. They will be sharing more information with site owners on how to investigate this security vulnerability on their site, which they will publish on their blog when it is ready. If a store was affected, the exposed information will be specific to what that site is storing but could include order, customer, and administrative information.

Is WooCommerce still safe to use?

Yes.

Incidents like this are uncommon, but do unfortunately sometimes happen.

Since learning of the vulnerability, the WooCommerce team has worked around the clock to ensure that a fix has been put in place, and users have been informed.

Our continued investment in platform security allows them to prevent the vast majority of issues – but in the rare cases that could potentially impact stores, they strive to fix quickly, communicate proactively, and work collaboratively with the WooCommerce Community.
