The Tutor LMS – eLearning and online course solution plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 3.8.3. This makes it possible for authenticated attackers, with tutor-level access and above, to view assignments for courses they don't teach which may contain sensitive information.
The Tutor LMS – eLearning and online course solution plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check while verifying webhook signatures on the "verifyAndCreateOrderData" function
in all versions up to, and including, 3.8.3. This makes it possible for unauthenticated attackers to bypass payment verification and mark orders as paid by submitting forged webhook requests with `payment_type` set to 'recurring'.
The Tutor LMS plugin for WordPress is vulnerable to bypass to user registration in versions up to, and including, 2.7.6. This is due to a missing check for the 'users_can_register' option in the 'register_instructor' function. This makes it possible for unauthenticated attackers to register as the default role on the site, even if registration is disabled.
The Tutor LMS plugin for WordPress is vulnerable to SQL Injection via the ‘rating_filter’ parameter in all versions up to, and including, 2.7.6 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
