Description
The LearnPress plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the question hint and explanation fields in all versions up to, and including, 4.4.9.1. This is due to insufficient input sanitization when these fields are saved through the question edit AJAX action, and insufficient output escaping when they are returned. This makes it possible for authenticated attackers with instructor or author-level access and above to inject arbitrary web scripts into questions. These scripts execute whenever a student or administrator views the affected question.
