What to do
- Replace it. A closed plugin gets no updates through WordPress, so any hole found from now on stays open.
- Deactivate and delete it once you have a replacement (Plugins → Deactivate → Delete). Deleting removes its files; deactivating alone leaves them on the server.
- If you ran a vulnerable version and something looks off (spam pages, strange admins, redirects), run the free scan, or have us clean it: Emergency Cleanup, $499.
With WP-CLI, once you have a replacement: wp plugin deactivate hel-online-classroom && wp plugin delete hel-online-classroom

medium 5.3 CVE-2026-6708 · published 2026-05-12

- Affected
- 1.0.3 and older
- Fixed in
- unknown
- Access needed (per CVSS)
- No login needed
- Range from
- CVE record (the advisory publisher) · score by Wordfence
Details from the advisory
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.
