Payrexx Payment Gateway for WooCommerce < 3.1.6 - Missing Authorization

Description

The Payrexx Payment Gateway for WooCommerce plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the payrexx_store_connect_settings() function in versions up to, and including, 3.1.5. This makes it possible for authenticated attackers, with subscriber-level access and above, to update settings.
