## Description

The Bonus for Woo plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 8.3.3 due to the plugin granting the shop_manager role the 'manage_options' and 'edit_users' capabilities on activation and never revoking them. This makes it possible for authenticated attackers with Shop Manager-level access and above to change arbitrary site options, such as the default registration role, and escalate their privileges to full administrator.
