## Description

The PiWeb Disable payment method / Partial payment for WooCommerce plugin for WordPress is vulnerable to unauthorized modification of data via the usage tracking admin-post action in all versions up to, and including, 1.1.10.9, due to a missing capability check and missing nonce validation in the handle_tracker_action() function. This makes it possible for authenticated attackers, with Subscriber-level access and above, to enable or disable the plugin's usage tracking option. Enabling it sends the site URL and the plugin, WordPress and WooCommerce versions to the vendor without the site administrator's consent.
