CVE-2026-104898

Online Scheduling and Appointment Booking System <= 28.4 - Insecure Direct Object Reference to Authenticated (Subscriber+) Privilege Escalation via 'id' and 'wp_user_id' Parameters via Query String / JSON Body

The Online Scheduling and Appointment Booking System – Bookly plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 28.4 via the 'id, wp_user_id' parameter due to missing validation on a user controlled key. This makes it possible for authenticated attackers, with subscriber-level access and above, to overwrite the WordPress account binding of any Bookly staff record, including those owned by administrators, effectively hijacking a higher-privileged staff member's account association and escalating privileges. Exploitation requires the attacking user to be linked to at least one Bookly staff record, which occurs by default whenever an admin enables the bookly_gen_allow_staff_edit_profile option (active on fresh installs) and links a WordPress user to a staff entry.

Academy LMS <= 4.0.3 - Missing Authorization to Authenticated (Custom+) Arbitrary Academy Comment Deletion via delete_lesson_comment AJAX — Attacker-Controlled course_id vs. Target comment_id

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