WordPress is a free and open-source content management system written in
PHP and paired with a MySQL or MariaDB database. In affected versions the
widgets editor introduced in WordPress 5.8 beta 1 has improper handling of
HTML input in the Custom HTML feature. This leads to stored XSS in the
custom HTML widget. This has been patched in WordPress 5.8. It was only
present during the testing/beta phase of WordPress 5.8.
