Action Required: Critical PHP Security Alert – What It Means for Your Website

What is this vulnerability?

A critical security issue was recently identified affecting servers running PHP—a coding language used by millions of websites across the web. If left unpatched, this flaw could potentially allow unauthorized users to execute harmful code on an affected server.

Security updates and temporary workarounds have been released to address the issue, but action is required on servers that run PHP.

Does this affect my website?

It depends entirely on how your website was built and where it is hosted:

• If your website is on WordPress, Drupal, Joomla, or a custom PHP platform:

  YES, your site likely relies on PHP. Your hosting server needs to be updated with the latest security patch as soon as possible.

• If your website is on Wix, Squarespace, or Shopify:

  NO, these platforms do not run on PHP, and their internal security teams manage all server updates automatically. You do not need to take any action.
  

What should you do next?

Because every website setup is unique, we strongly recommend reaching out to your web designer, developer, or web hosting provider as soon as possible.

Here is a quick template you can copy and paste into an email to them:
