What is CVE-2019-12517?

An XSS vulnerability in the SlickQuiz plugin for WordPress allows unauthenticated users to exploit the save_quiz_score functionality at the /wp-admin/admin-ajax.php endpoint. This vulnerability permits attackers to submit quiz solutions, which are stored in the database and later displayed in the WordPress backend. As a result, when these solutions contain malicious scripts, they can be triggered within the admin interface for all users having at least Subscriber rights. The lack of proper validation and sanitization for input fields, such as name and email, enables the execution of these scripts, putting all users at risk.
