Tutor LMS < 2.7.4 - Authenticated (Instructor+) Stored Cross-Site Scripting

Description

The Tutor LMS plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to, and including, 2.7.3 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with instructor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
