Themeum vulnerabilities

The Tutor LMS – eLearning and online course solution plugin for WordPress is vulnerable to Insecure Direct Object Reference in versions up to and including 3.9.9. This is due to the `get_course_id_by()` function unconditionally trusting the user-supplied `course` GET parameter as the authoritative course ID for content ownership lookups, which is then consumed by `can_user_manage()`, the plugin's sole authorization gate for instructor-level operations, causing it to evaluate instructor membership against the attacker-controlled course rather than the course that actually owns the target content object. This makes it possible for authenticated attackers, with instructor-level access and above, to perform unauthorized operations on any other instructor's course content, including permanently deleting lessons, assignments, quizzes (with cascading deletion of all student attempt data), topics, announcements, and Q&A threads, as well as creating or modifying lessons, topics, and announcements in victim courses, manipulating student quiz grades, and reading unpublished lesson and quiz content.

The Tutor LMS plugin for WordPress is vulnerable to SQL Injection in versions up to and including 3.9.8. This is due to insufficient escaping on the 'date' parameter combined with direct interpolation into a SQL fragment before being passed to $wpdb->prepare(). This makes it possible for authenticated attackers with Admin-level access and above to append additional SQL queries and extract sensitive information from the database.

The Tutor LMS – eLearning and online course solution plugin for WordPress is vulnerable to unauthorized course content manipulation in versions up to and including 3.9.8. This is due to a missing authorization check in the tutor_update_course_content_order() function. The function only validates the nonce (CSRF protection) but does not verify whether the user has permission to manage course content. The can_user_manage() authorization check only executes when the 'content_parent' parameter is present in the request. When this parameter is omitted, the function proceeds directly to save_course_content_order() which manipulates the wp_posts table without any authorization validation. This makes it possible for authenticated attackers with subscriber-level access and above to detach all lessons from any topic, move lessons between topics, and modify the menu_order of course content, effectively allowing them to disrupt the structure of any course on the site.

Missing Authorization vulnerability in Themeum Tutor LMS tutor allows Exploiting Incorrectly Configured Access Control Security Levels.This issue affects Tutor LMS: from n/a through <= 3.9.7.

The Tutor LMS – eLearning and online course solution plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 3.9.7. This is due to missing authorization checks in the `save_course_content_order()` private method, which is called unconditionally by the `tutor_update_course_content_order` AJAX handler. While the handler's `content_parent` branch includes a `can_user_manage()` check, the `save_course_content_order()` call processes attacker-supplied `tutor_topics_lessons_sorting` JSON without any ownership or capability verification. This makes it possible for authenticated attackers with Subscriber-level access or above to detach lessons from topics, reorder course content, and reassign lessons between topics in any course, including admin-owned courses, by sending a crafted AJAX request with manipulated topic and lesson IDs.

The Tutor LMS – eLearning and online course solution plugin for WordPress is vulnerable to unauthorized private course enrollment in all versions up to, and including, 3.9.7. This is due to missing post_status validation in the `enroll_now()` and `course_enrollment()` functions. Both enrollment endpoints verify the nonce, user authentication, and whether the course is purchasable, but fail to check if the course has a `private` post_status. This makes it possible for authenticated attackers with Subscriber-level access or above to enroll in private courses by sending a crafted POST request with the target course ID. The enrollment record is created in the database and the private course title and enrollment status are exposed in the subscriber's dashboard, though WordPress core access control prevents the subscriber from viewing the actual course content (returns 404). Enrollment in private courses should be restricted to users with the `read_private_posts` capability.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in Themeum Qubely qubely allows Stored XSS.This issue affects Qubely: from n/a through <= 1.8.14.

Authorization Bypass Through User-Controlled Key vulnerability in Themeum Tutor LMS tutor allows Exploiting Incorrectly Configured Access Control Security Levels.This issue affects Tutor LMS: from n/a through <= 3.9.4.

Missing Authorization vulnerability in Themeum Tutor LMS tutor allows Exploiting Incorrectly Configured Access Control Security Levels.This issue affects Tutor LMS: from n/a through <= 3.9.5.

The Tutor LMS – eLearning and online course solution plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 3.9.5. This is due to missing authorization checks in the `ajax_coupon_details()` function, which only validates nonces but does not verify user capabilities. This makes it possible for authenticated attackers, with Subscriber-level access and above, to retrieve sensitive coupon information including coupon codes, discount amounts, usage statistics, and course/bundle applications.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in Themeum Tutor LMS BunnyNet Integration tutor-lms-bunnynet-integration allows DOM-Based XSS.This issue affects Tutor LMS BunnyNet Integration: from n/a through <= 1.0.0.

The Tutor LMS – eLearning and online course solution plugin for WordPress is vulnerable to unauthorized attachment deletion due to a missing capability check on the `delete_existing_user_photo` function in all versions up to, and including, 3.9.4. This makes it possible for authenticated attackers, with subscriber level access and above, to delete arbitrary attachments on the site.

The Tutor LMS – eLearning and online course solution plugin for WordPress is vulnerable to unauthorized course completion in all versions up to, and including, 3.9.2. This is due to missing enrollment verification in the 'mark_course_complete' function. This makes it possible for authenticated attackers, with subscriber level access and above, to mark any course as completed.

The Tutor LMS – eLearning and online course solution plugin for WordPress is vulnerable to unauthorized course enrollment in all versions up to, and including, 3.9.3. This is due to a missing capability check and purchasability validation in the `course_enrollment()` AJAX handler. This makes it possible for authenticated attackers, with subscriber level access and above, to enroll themselves in any course without going through the proper purchase flow.

The Tutor LMS – eLearning and online course solution plugin for WordPress is vulnerable to unauthorized modification and deletion of data due to a missing capability check on the 'bulk_action_handler' and 'coupon_permanent_delete' functions in all versions up to, and including, 3.9.3. This makes it possible for authenticated attackers, with subscriber level access and above, to delete, activate, deactivate, or trash arbitrary coupons.

The Tutor LMS – eLearning and online course solution plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability check on the get_order_by_id() function in all versions up to, and including, 3.9.3. This makes it possible for authenticated attackers, with Subscriber-level access and above, to enumerate order IDs and exfiltrate sensitive data (PII), such as student name, email address, phone number, and billing address.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in Themeum Tutor LMS Elementor Addons tutor-lms-elementor-addons allows Stored XSS.This issue affects Tutor LMS Elementor Addons: from n/a through <= 3.0.1.

The Tutor LMS – eLearning and online course solution plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 3.8.3. This makes it possible for authenticated attackers, with tutor-level access and above, to view assignments for courses they don't teach which may contain sensitive information.

The Tutor LMS Pro – eLearning and online course solution plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 3.8.3 due to missing validation on a user controlled key when viewing and editing assignments through the tutor_assignment_submit() function. This makes it possible for authenticated attackers, with Subscriber-level access and above, to view and edit assignment submissions of other students.
