Two critical vulnerabilities in PHP itself
PHP, the language WordPress, WooCommerce, Magento and most content management systems run on, has two critical flaws, both rated 9.2 out of 10. The fixes are due at 1:00am AEDT on Thursday 22 October 2026, and the ASD says every version from PHP 5 onwards may be affected. If your website runs on PHP, make sure whoever manages its server is ready to update the moment the release lands.
