Technical details
The vulnerability is a stored cross-site scripting (XSS) flaw in the plugin's question creation functionality. The vulnerable component fails to properly escape the "required" setting of polar-type questions before outputting it into an unquoted HTML attribute. An authenticated attacker with contributor-level access or above can inject arbitrary JavaScript via the REST API endpoint /wp-json/quiz-survey-master/v1/questions/. The payload breaks out of the unquoted data-is_required attribute and executes in the browser of any user viewing the quiz. The attack requires contributor-level access and a quiz embedded on a public page via the [mlw_quizmaster] shortcode. The vulnerability was fixed in version 11.2.2.
