FKIE_CVE-2024-10393

Vulnerability from fkie_nvd - Published: 2024-11-21 11:15 - Updated: 2026-06-17 06:55
Severity
5.3 (Medium) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N
Summary
The Tutor LMS plugin for WordPress is vulnerable to bypass to user registration in versions up to, and including, 2.7.6. This is due to a missing check for the 'users_can_register' option in the 'register_instructor' function. This makes it possible for unauthenticated attackers to register as the default role on the site, even if registration is disabled.
