Masteriyo LMS – LMS Course Builder, Quizzes & Certificates < 2.3.1 - Authenticated (Subscriber+) Stored Cross-Site Scripting

Description

The Masteriyo LMS – LMS Course Builder, Quizzes & Certificates plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to, and including, 2.3.0 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
