Important notice ·
PHP needs an update. Your website probably does too.
You never see it, but on most websites PHP is working in the background.
WordPress, Joomla, TYPO3, Drupal, Shopware, WooCommerce, Magento, Nextcloud and many more – they all run on PHP. On 21 October, two serious flaws in PHP became known. They let outsiders run their own programs on your server without a password, and first attempts have already been seen. The good news: an update closes both gaps.
What you need to do now
- Please check whether you're running PHP – and which version.That's the case for all the systems mentioned above. You can usually see the version in the admin area of your hosting or your website.
- Update to at least one of these versions.It's the only way to close the gap:
8.5.12 · 8.4.27 · 8.3.36 · 8.2.35. Stay within your version series – 8.3.x becomes 8.3.36. That way your website keeps running as before. - Are you using PHP 8.1 or older?There are no regular updates for it any more. Move to a current version straight away – in consultation with whoever makes your website or software, so that everything keeps working.
- No update possible, or not sure?Then please take the site offline immediately until it's secured. Better briefly unavailable than open to outsiders. Get in touch – we'll help you.
