Vulnerability from github – Published: 2026-05-12 09:31 – Updated: 2026-05-12 09:31

Details

The HEL Online Classroom: AI-powered Online Classrooms plugin for WordPress is vulnerable to Missing Authorization in all versions up to, and including, 1.0.3. This is due to a missing capability check on a REST API endpoint registered with a permission_callback of '__return_true', which bypasses all WordPress authentication and authorization checks. This makes it possible for unauthenticated attackers to delete any classroom record by supplying its ID in the request, resulting in permanent data loss.

Severity

5.3 (Medium)


                  
                    CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N
