What the vulnerability does

01Description

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'.

Explanation of Vulnerability in Simple Terms

02Summary

Tutor LMS versions up to 3.8.3 lack proper authorization checks, allowing unauthenticated attackers to modify data through network requests. The vulnerability does not expose sensitive information or disrupt service availability, but permits unauthorized changes to course or user content. Site administrators should update to a version newer than 3.8.3 to restore access controls.
