What it is

The MStore API WordPress plugin before 4.21.0 does not perform authorization or purchase-ownership checks on its REST product-review creation route, allowing an unauthenticated attacker to create WooCommerce product reviews with an attacker-chosen reviewer name, email and star rating on stores configured to accept reviews only from verified owners.
