MStore API WordPress plugin vulnerabilities

The MStore API WordPress plugin before 3.9.8 does not sanitize and escape a parameter before using it in a SQL statement, leading to a Blind SQL injection exploitable by unauthenticated users. This is only exploitable if the site owner elected to pay to get access to the plugins' pro features and uses the woocommerce-appointments plugin.

The MStore API WordPress plugin before version 3.9.9 allows visitors to create user accounts with any role via its REST API endpoint. This is only exploitable if the site owner paid for access to the plugin's pro features.

The MStore API WordPress plugin before 4.22.1 does not restrict which order fields a customer may update. Any authenticated user with a self-registerable account can change the status of their own unpaid order to a paid or fulfilled state and receive goods without paying.

The MStore API WordPress plugin before 3.9.7 does not secure most of its AJAX actions by implementing privilege checks, nonce checks, or a combination of both.
