WPify Woo <= 5.4.16 - Authenticated (Shop Manager+) Privilege Escalation via Arbitrary Option Update via save_option REST Endpoint

Summary

The Wpify Woo plugin for WordPress is vulnerable to Privilege Escalation in versions up to, and including, 5.4.16. This is due to the SettingsApi::save_option() REST route (POST /wp-json/wpify-woo/v1/option) passing the request-supplied 'option' and 'data' parameters directly to update_option() without any option-name allowlist or value sanitization, while the permission_callback only verifies the manage_woocommerce capability. This makes it possible for authenticated attackers, with Shop Manager-level access and above, to elevate their privileges to Administrator by overwriting arbitrary WordPress options (for example setting default_role to administrator and users_can_register to 1, or disabling security plugins via active_plugins).
