Sep 24, 2026Masteriyo LMS: Does not restrict access to quiz answer keysCVE-2026-82850 · fixed in 3.4.2 · reported by WPScanMedium 4.3
The Masteriyo LMS WordPress plugin before 3.4.2 does not restrict access to quiz answer keys, allowing any authenticated user, such as a student, to retrieve the correct answers for any quiz on the site, including quizzes in courses they are not enrolled in.

Sep 24, 2026Masteriyo LMS: Does not verify that the user making the request owns the course-progress records being returnedCVE-2026-82849 · fixed in 3.4.2 · reported by WPScanMedium 4.3

Sep 12, 2026Masteriyo LMS: Does not prevent user-supplied values heldCVE-2026-82845 · fixed in 3.4.1 · reported by WPScanCritical 9.9
The Masteriyo LMS WordPress plugin before 3.4.1 does not prevent user-supplied values held as metadata from being deserialized when they are read back, allowing users with a minimal account to inject arbitrary PHP objects and, by way of a class shipped in a library bundled with the Masteriyo LMS WordPress plugin before 3.4.1, write and execute arbitrary code on the server. A weaker form of the same issue is reachable without an account and yields an arbitrary file write rather than code execution.

Apr 8, 2026Masteriyo LMS – Online Course Builder for eLearning, LMS & Education: Authorization Bypass Through User-Controlled KeyCVE-2026-5167 · affects up to 2.1.7 · reported by WordfenceMedium 5.3
The Masteriyo LMS – Online Course Builder for eLearning, LMS & Education plugin for WordPress is vulnerable to Authorization Bypass Through User-Controlled Key in versions up to and including 2.1.7. This is due to insufficient webhook signature verification in the handle_webhook() function. The webhook endpoint processes unauthenticated requests and only performs signature verification if both the webhook_secret setting is configured AND the HTTP_STRIPE_SIGNATURE header is present. Since webhook_secret defaults to an empty string, the webhook processes attacker-controlled JSON payloads without any verification. This makes it possible for unauthenticated attackers to send fake Stripe webhook events with arbitrary order_id values in the metadata, mark any order as completed without payment, and gain unauthorized access to paid course content.
