Descriptions

The MStore API WordPress plugin before 3.9.9 does not prevent visitors from creating user accounts with the role of their choice via their wholesale REST API endpoint. This is only exploitable if the site owner paid to access the plugin's pro features.

The MStore API plugin for WordPress is vulnerable to Privilege Escalation in versions up to, and including, 3.9.8 due to insufficient restriction on roles supplied during registration through the /register REST route. This allows unauthenticated attackers register as administrators.
