SA-CONTRIB-2015-027 - Quizzler - Cross Site Scripting (XSS)

The Quizzler module allows you to create online quizzes and tests. Quizzes are nodes with questions attached.

The module does not sanitize user input in the node title when displaying it on the page, allowing a malicious user to inject code, a Cross Site Scripting (XSS) attack.

This vulnerability is mitigated by the fact that an attacker must have a role that allows them to create nodes or edit nodes that are assigned as quizzes.
