What the vulnerability does
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.
Explanation of Vulnerability in Simple Terms
Tutor LMS versions up to 2.7.6 contain an access control flaw that allows unauthenticated attackers to modify data on the site. The vulnerability requires no special setup or user interaction. Site administrators should update to a version newer than 2.7.6 to prevent unauthorized changes to course content or settings.
What an attacker can do
Modify course data, settings, or other site content without logging in.
Potential impact on your site
Attackers can alter course content, student records, or plugin settings without permission.
Conditions required to exploit
Network access to the site; no authentication or user interaction required.
