CVE-2019-9787

WordPress before 5.1.1 does not properly filter comment content, leading to
Remote Code Execution by unauthenticated users in a default configuration.
This occurs because CSRF protection is mishandled, and because Search
Engine Optimization of A elements is performed incorrectly, leading to XSS.
The XSS results in administrative access, which allows arbitrary changes to
.php files. This is related to wp-admin/includes/ajax-actions.php and
wp-includes/comment.php.
