Description
The WC Vendors – WooCommerce Multivendor, WooCommerce Marketplace, Product Vendors plugin for WordPress is vulnerable to unauthorized access via the 'do_update_wcvendors' action in all versions up to, and including, 2.7.2.2, due to a missing capability check and missing nonce verification in the install_actions() function, which is hooked to admin_init. admin_init also fires for requests to admin-ajax.php and admin-post.php, so the handler runs for logged-out visitors. This makes it possible for unauthenticated attackers to queue and start the plugin's pending database update routines before a site administrator approves them, and to add the database update notice to the admin area.
