Impact

CVSS 5.4 (Medium) reflects network-accessible endpoints with low attack complexity and low privilege requirements, limited to confidentiality and integrity impacts without availability impact. The CVSS vector (AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N) confirms unauthenticated access is NOT required-only Subscriber-level role is needed, a common default permission tier in WordPress installations. Real-world risk is moderate but operationally significant: the vulnerability enables privilege escalation within the WordPress permission model by allowing Subscribers to gain unauthorized access to course enrollment records and private course metadata intended only for administrators or instructors. SSVC considerations: exploitation is straightforward (no special conditions needed beyond valid Subscriber credentials), the technical impact is focused (enrollment data exposure, not remote code execution), but organizations using private courses for access-controlled content face direct confidentiality and integrity compromise. No KEV status or active exploitation confirmation provided, suggesting this is not yet widely exploited in the wild, though the low barrier to exploitation (standard WordPress Subscriber role) makes post-patch deployment critical.

Exploit ScenarioDerived

An authenticated user with WordPress Subscriber-level role (the default for site users) sends a crafted POST request to the enrollment endpoint with a private course ID, bypassing the missing post_status check. The enrollment record is created in the database, and the private course title and enrollment status now appear in the attacker's subscriber dashboard, leaking metadata about restricted content. While WordPress core access control prevents the Subscriber from viewing the actual course materials (returning 404 on access attempts), the enrollment record and metadata exposure constitutes unauthorized information disclosure about the private course structure and enrollment state.

AnalysisAIv1 – Apr 11, 2026

Tutor LMS plugin for WordPress up to version 3.9.7 allows authenticated subscribers to enroll in private courses due to missing post_status validation in enrollment functions, exposing private course metadata in user dashboards despite WordPress core preventing actual content access. The vulnerability requires subscriber-level authentication but affects confidentiality and integrity, with confirmed patches available in version 3.9.8.

RemediationAI

Vendor-released patch: Tutor LMS version 3.9.8 or later. Sites running version 3.9.7 or earlier must upgrade immediately to 3.9.8 to apply post_status validation in the enrollment functions. The patch corrects the enroll_now() and course_enrollment() functions to verify that enrolled courses are not in private post_status before allowing enrollment by Subscriber-level users. WordPress administrators can verify the patch is in place by reviewing the Course.php file at the relevant code locations (https://plugins.trac.wordpress.org/changeset?old_path=%2Ftutor/tags/3.9.7&new_path=%2Ftutor/tags/3.9.8). No workarounds are available; patching is the only remediation.

Technical ContextAI · show details

The vulnerability exists in the enroll_now() and course_enrollment() functions within the Tutor LMS plugin's Course.php class. These endpoints perform nonce verification, user authentication checks, and purchasability validation but fail to implement CWE-862 (Missing Authorization) by omitting verification of the course's post_status field. In WordPress, posts with private post_status should only be readable by users with the read_private_posts capability; Tutor LMS does not enforce this restriction at the enrollment layer. While WordPress core access control prevents direct content viewing (returning 404), the enrollment record created in the database and metadata exposure in the subscriber dashboard constitute unauthorized information disclosure and unauthorized state modification.

DescriptionCVE.org

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.
