Wordpress is an open source CMS. A user with the ability to upload files (like an Author) can exploit an XML parsing issue in the Media Library leading to XXE attacks. This requires WordPress installation to be using PHP 8. Access to internal files is possible in a successful XXE attack. This has been patched in WordPress version 5.7.1, along with the older affected versions via a minor release. We strongly recommend you keep auto-updates enabled.
The Strapi framework before 3.0.0-beta.17.8 is vulnerable to Remote Code Execution in the Install and Uninstall Plugin components of the Admin panel, because it does not sanitize the plugin name, and attackers can inject arbitrary shell commands to be executed by the execa function.
