CVE-2024-10393Network attack vector

Unauthorized account creation via ignored registration setting

Published Nov 21, 2024 · Updated Apr 8, 2026

Improper access control in Themeum Tutor LMS 2.7.6 and earlier allows remote attackers to register accounts while registration is disabled. The register_instructor method processes the tutor_register_instructor action and inserts a WordPress user without first checking users_can_register. Reachability requires the instructor-registration route and its form nonce; successful exploitation creates an account with the site's configured default role.
