Summary

The MasterStudy LMS plugin for WordPress before 3.7.50 contains a missing authorization flaw (CWE-862). Any authenticated user, including Subscribers, can trigger the stm_lms_send_test_email_ajax AJAX action without capability or nonce checks. An attacker can invoke it directly or through cross-site request forgery to cause an uncaught PHP fatal error, which discloses the absolute filesystem path of the plugin when display_errors is enabled.
