Kodezen Academy LMS – AI Course Builder, Quizzes, Certificates & eLearning vulnerabilities

The Academy LMS – AI Course Builder, Quizzes, Certificates & eLearning plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 4.0.3. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with custom-level access and above, to permanently delete arbitrary Academy lesson comments and their replies authored by any user, including administrators, across courses they do not instruct. This is exploitable by any user registered as an Academy instructor for at least one course, as they can supply their own course_id to pass the instructor check while targeting comments belonging to entirely different courses.

The Academy LMS – AI Course Builder, Quizzes, Certificates & eLearning plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 4.0.3. This is due to the `add_child()` function calling `add_role('academy_student')` on any existing account resolved from the attacker-supplied `email` parameter before `Store::link()` validates the guardian-ward relationship, and failing to roll back that role write when `Store::link()` returns a `WP_Error`. This makes it possible for authenticated attackers with the `academy_guardian` role or higher to elevate any existing WordPress account — including their own — to the `academy_student` role, gaining `edit_posts` (Contributor-equivalent) capabilities and, when the student file-upload setting is enabled, `upload_files` (Author-equivalent) capabilities not granted to the guardian role. When a guardian supplies their own email address, `email_exists()` resolves to their own user ID, causing `Store::link()` to reject the self-link, but because the `add_role()` call has already executed and is never reversed, the academy_student role grant on their own account persists permanently.
