Name of the Vulnerable Software and Affected Versions MasterStudy LMS plugin for WordPress versions up to, and including, 3.3.1

Description The issue is due to insufficient validation checks within the register user() function called by the 'wp ajax nopriv stm lms register' AJAX action. This allows unauthenticated attackers to register a user with administrator-level privileges when MasterStudy LMS Pro is installed and the LMS Forms Editor add-on is enabled.

Recommendations For MasterStudy LMS plugin for WordPress versions up to, and including, 3.3.1: Update the plugin immediately to secure the WordPress site. As a temporary workaround, consider disabling the register user() function or restricting access to the 'wp ajax nopriv stm lms register' AJAX action until a patch is available.
