To protect your site, it's highly recommended to update to the latest stable versions of Craft CMS: 3.9.14, 4.13.2, or 5.5.2. If you're unable to upgrade right away, the best mitigation step is to disable the register_argc_argv
option in your php.ini
configuration. By taking these precautions, you can ensure your Craft CMS-powered website remains secure and protected from potential attacks.
