Tutor LMS <= 4.0.1 - Authenticated (Administrator+) SQL Injection via 'coupon_code' Parameter

Tutor LMS – eLearning and online course solution: Currently marked unpatched

Affected versions: *-4.0.1

Vulnerability type: CWE-89 Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')

Affected software, patched versions and attribution

The Tutor LMS – eLearning and online course solution plugin for WordPress is vulnerable to generic SQL Injection via the 'coupon_code' parameter in all versions up to, and including, 4.0.1 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with administrator-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

Tutor LMS <= 4.0.0 - Authenticated (Subscriber+) SQL Injection via Stored Quiz Answer Array

Tutor LMS – eLearning and online course solution: Currently marked unpatched

Affected versions: *-4.0.0

Vulnerability type: CWE-89 Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')

Affected software, patched versions and attribution

The Tutor LMS – eLearning and online course solution plugin for WordPress is vulnerable to generic SQL Injection via Stored Quiz Answer Array in all versions up to, and including, 4.0.0 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with custom-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. The payload is stored at quiz-attempt time via the wp_ajax_tutor_quiz_abandon handler, but the injected SQL executes only when a privileged user or Tutor REST API key holder requests the /wp-json/tutor/v1/quiz-attempt-details/{id} endpoint, making this a second-order (stored) injection chain.

Tutor LMS <= 3.9.9 - Insecure Direct Object Reference to Authenticated (Instructor+) Arbitrary Post Deletion via 'course' GET Parameter

Tutor LMS – eLearning and online course solution: Currently marked unpatched

Affected versions: *-3.9.9

Vulnerability type: CWE-639 Authorization Bypass Through User-Controlled Key

Affected software, patched versions and attribution

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.

Tutor LMS <= 3.9.8 - Authenticated (Subscriber+) Arbitrary Course Content Manipulation via tutor_update_course_content_order

Tutor LMS – eLearning and online course solution: Currently marked unpatched

Affected versions: *-3.9.8

Vulnerability type: CWE-862 Missing Authorization

Affected software, patched versions and attribution

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.

Tutor LMS – eLearning and online course solution: Currently marked unpatched

Affected versions: *-3.9.7

Vulnerability type: CWE-639 Authorization Bypass Through User-Controlled Key

Affected software, patched versions and attribution

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.

Tutor LMS <= 3.9.7 - Missing Authorization to Authenticated (Subscriber+) Unauthorized Private Course Enrollment

Tutor LMS – eLearning and online course solution: Currently marked unpatched

Affected versions: *-3.9.7

Vulnerability type: CWE-862 Missing Authorization

Affected software, patched versions and attribution

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.

Tutor LMS <= 3.9.7 - Missing Authorization to Unauthenticated Arbitrary Billing Profile Overwrite via 'order_id' Parameter

Tutor LMS – eLearning and online course solution: Currently marked unpatched

Affected versions: *-3.9.7

Vulnerability type: CWE-862 Missing Authorization

Affected software, patched versions and attribution

The Tutor LMS – eLearning and online course solution plugin for WordPress is vulnerable to an Insecure Direct Object Reference in all versions up to, and including, 3.9.7. This is due to missing authentication and authorization checks in the `pay_incomplete_order()` function. The function accepts an attacker-controlled `order_id` parameter and uses it to look up order data, then writes billing fields to the order owner's profile (`$order_data->user_id`) without verifying the requester's identity or ownership. Because the Tutor nonce (`_tutor_nonce`) is exposed on public frontend pages, this makes it possible for unauthenticated attackers to overwrite the billing profile (name, email, phone, address) of any user who has an incomplete manual order, by sending a crafted POST request with a guessed or enumerated `order_id`.
