Bonanza – WooCommerce Free Gifts Lite <= 1.0.0 - Missing Authorization to Authenticated (Subscriber+) Opt In Success

The Bonanza – WooCommerce Free Gifts Lite plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the xlo_optin_call() function in all versions up to, and including, 1.0.0. This makes it possible for authenticated attackers, with Subscriber-level access and above, to set the opt in status to success.
