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 addchild() function calling addrole('academystudent') 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 WPError. This makes it possible for authenticated attackers with the academyguardian role or higher to elevate any existing WordPress account — including their own — to the academystudent role, gaining editposts (Contributor-equivalent) capabilities and, when the student file-upload setting is enabled, uploadfiles (Author-equivalent) capabilities not granted to the guardian role. When a guardian supplies their own email address, emailexists() resolves to their own user ID, causing Store::link() to reject the self-link, but because the addrole() call has already executed and is never reversed, the academystudent role grant on their own account persists permanently.

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 courseid to pass the instructor check while targeting comments belonging to entirely different courses.

The Academy LMS WordPress plugin before 4.0.0 does not verify that a quiz question belongs to the course the requesting user is authorized to access before returning that question's answer options, allowing any authenticated user with access to a single course, such as an enrolled student, to read the quiz answer options of questions belonging to other courses they are not enrolled in.

The Academy LMS WordPress plugin before 4.0.0 does not verify course enrollment or object ownership when returning a lesson's content through one of its REST API routes, allowing users with a self-registerable student account to read the full content of arbitrary lessons, including lessons of paid or private courses they are not enrolled in.

The Academy LMS WordPress plugin before 3.8.1 does not verify ownership of a user-supplied user identifier in several of its lesson AJAX handlers, allowing authenticated users with subscriber-level access to read and modify other users' lesson notes and mark other users' lesson content as completed.

The Academy LMS – WordPress LMS Plugin for Complete eLearning Solution plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 3.3.8 via the 'enqueuesocialloginscript' function. This makes it possible for unauthenticated attackers to extract sensitive data including the Facebook App Secret if Facebook Social Login is enabled.

The Academy LMS – eLearning and online course solution for WordPress plugin for WordPress is vulnerable to privilege escalation in all versions up to, and including, 1.9.19. This is due to plugin allowing arbitrary user meta updates through the saveduserinfo() function. This makes it possible for authenticated attackers, with minimal permissions such as students, to elevate their user role to that of an administrator.
