Product Catalog Enquiry for WooCommerce by MultiVendorX <= 5.0.5 - Cross-Site Request Forgery via REST API

The Product Catalog Enquiry for WooCommerce by MultiVendorX plugin for WordPress is vulnerable to cross-site request forgery due to an improper capability check on the 'catalog_permission' function in versions up to, and including, 5.0.5. While the REST endpoints are only initialized for administrator users, the fact that the 'catalog_permission' returns true means that the REST route is treated as unauthenticated and thus does not require a REST nonce. This makes it possible for unauthenticated attackers to save enquiries.
