Description

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.

Analysis

Tutor LMS plugin for WordPress through version 3.9.4 fails to validate user permissions on the delete_existing_user_photo function, allowing authenticated subscribers and higher-privileged users to delete arbitrary attachments. This integrity and availability vulnerability requires an active WordPress account but no elevated privileges, making it exploitable by low-level users to disrupt site content.
