What is CVE-2026-3360?

The Tutor LMS plugin for WordPress has a security flaw that allows unauthenticated attackers to manipulate the pay_incomplete_order() function. This vulnerability occurs due to a lack of proper authentication and authorization checks. Attackers can send crafted POST requests containing an order_id parameter that they control. If successful, this can lead to unauthorized access and modifications of any user's billing profile, including their name, email, phone number, and address. The issue arises because the Tutor nonce is publicly accessible, making it easier for malicious users to exploit this loophole without needing authentication.
