CVE-2026-9341
MediumCVSS 4.3Summary
The Academy LMS plugin for WordPress up to version 3.8.0 is vulnerable to Insecure Direct Object Reference (IDOR) in the 'save_lesson_note', 'get_lesson_note', and 'complete_lesson_video' AJAX handlers due to missing validation on a user-controlled key. This allows authenticated attackers with Subscriber-level access or higher to read, overwrite, or delete private lesson notes of any other user (including administrators) and falsify lesson-completion progress for arbitrary users.
Risk Assessment
The organization faces exposure of sensitive educational data, manipulation of course progress, and potential compromise of learning process integrity, which can lead to loss of user trust and audit issues.
Recommendation
Immediately update the Academy LMS plugin to version 3.8.1 or later, which includes a fix for the IDOR vulnerability. If an update is not possible, temporarily restrict access to the AJAX handlers for low-privileged users.
