What the vulnerability does
The Tutor LMS – eLearning and online course solution plugin for WordPress is vulnerable to unauthorized attachment deletion due to a missing capability check on the `delete_existing_user_photo` function in all versions up to, and including, 3.9.4. This makes it possible for authenticated attackers, with subscriber level access and above, to delete arbitrary attachments on the site.
Explanation of Vulnerability in Simple Terms
Tutor LMS versions up to 3.9.4 lack proper authorization checks, allowing authenticated users to modify or delete content they should not have access to. An attacker with a low-privilege account can change course data or disable features without proper permission validation. This affects the integrity of course content and site availability.
What an attacker can do
Modify or delete course content and settings without proper authorization.
Potential impact on your site
Course instructors or admins may find their content altered or deleted by unauthorized users with basic accounts.
Conditions required to exploit
