Website security check · October 2026
Is your website affected?
Enter your website below to check whether it could be affected by the latest security issue.
Why this matters
A serious security issue has been found in PHP, software used to run many websites, including WordPress sites. This check helps you decide what to do next. Your hosting provider can confirm whether your website has the fix.
Who can fix it?
Your hosting provider needs to apply the PHP security update. Updating WordPress or its plugins won’t fix this issue. Some hosts received the fix before the announcement, so your website’s version number or last update date alone won’t tell you whether it’s protected.
