Upgrade the MasterStudy LMS plugin to version 3.7.50 or later, where this vulnerability is fixed. No other mitigations are indicated by the vendor advisory.
Description
The MasterStudy LMS plugin for WordPress versions before 3.7.50 contains a missing authorization vulnerability. This flaw allows any authenticated user, including those with minimal privileges such as Subscribers, to invoke the stm_lms_send_test_email_ajax AJAX action without proper capability or nonce validation. Exploiting this can cause an uncaught PHP fatal error that, if error display is enabled, reveals the absolute filesystem path of the plugin.
