Why the WooCommerce Critical Vulnerability Shows the Value of Maintaining Your Website

Why the WooCommerce Critical Vulnerability Shows the Value of Maintaining Your Website

A vulnerability with one of your themes or plugins is never ideal. However, when the plugin in question is the number one e-commerce platform in the world, you could upgrade the feeling to “catastrophic.” WooCommerce is the plugin in question, and it had to be patched fast to fix a critical vulnerability affecting all users.

While the issue is now patched, it does raise the question: What should you do if a vulnerability like this crops up again, and how can you mitigate it? The answer has some complexities, but you have to employ a robust maintenance plan and maybe hire experts to look after your site.

Over the next few sections, we’ll discuss the recent vulnerability with WooCommerce. We will give you the context for how development teams responded and how you can prevent this kind of situation from affecting you in the future.

Explaining the WooCommerce Critical Vulnerability

Despite our heading, it’s tough for us to explain the security flaw found in WooCommerce – it hasn’t yet been disclosed, other than that it’s a “critical vulnerability.” Still, it is important enough that there was a 24-hour turnaround between disclosing the issue and patching it.

The vulnerability notice came through Automattic’s HackerOne page. For the unaware, this is a ‘bug bounty’ site where a company will pay ethical hackers to find exploits in its software.

This isn’t only a WooCommerce issue; it also affects the companion WooCommerce Blocks plugin. As such, almost every site running WooCommerce 3.3–5.5 and/or WooCommerce Blocks 2.5–5.5 needs to be updated.

The Response to the Vulnerability

The turnaround between the ethical and responsible disclosure to resolution was around a day. Given the scope of the vulnerability, this is a fantastic response from the WooCommerce Support Team.

The developers created a patch fix for over 90 versions of the e-commerce plugin back to version 3.3. This saw automatic deployment to all affected sites.

While the team is still investigating the issue, they recommend that site owners update passwords as a precaution. There is no suggestion that any site has been affected yet. Even so, there’s been a rapid response to a potentially ruinous situation.

How Regular Site Maintenance Can Mitigate the Impact of Vulnerabilities

We admit that without regularly disassembling every theme and plugin to inspect its code, it’s hard to know whether an issue will arise.

Our advice is to remain vigilant when it comes to new updates. There’s value in waiting until the dust has settled on a new update before applying it. In contrast, you may still run into an issue when you update, mainly if the vulnerability is found later.

As such, you need to ensure your site can handle malicious attacks. There are a few ways you can do this:

  • As noted, give yourself a two-week window to watch for vulnerabilities or other issues. At that time, you should be safe to update. Of course, if the current patch fixes a vulnerability, you should immediately update.
  • Install a dedicated Web Application Firewall (WAF) at the server level to create a suitable barrier in case of attacks. A plugin like WordFence includes a WAF, but this isn’t a server-side solution. Instead, Sucuri and Cloudflare both offer this option.
  • Keep regular backups if there’s a breach and you need to restore your site. This is more about mitigation than active prevention – a safety net in case the worst happens.

In addition, you can implement an auditing and maintenance plan to help plug leaks in your security provision. You can go further than this and consider installing all updates on a staging site while you wait out the two-week window.

You may consider using extra login security, such as Two-Factor Authentication (2FA). While this might not stop any specific threat, shoring up your site like this makes it as safe as possible. With your backup as a safety net, you have everything in place to protect your site as well as possible.
