Researcher Rafshanzani Suhada
Description

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'.
