ShopEngine Elementor WooCommerce Builder Addon <= 4.9.4 - Authenticated (Shop Manager+) Privilege Escalation to WXR Import '<wp_option>' Nodes

The ShopEngine Elementor WooCommerce Builder Addon – All in One WooCommerce Solution plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 4.9.4. This is due to the `rum_importer()` function being registered on the WordPress core `import_start` action hook with no plugin-owned capability check and no allowlist filtering, causing arbitrary `<wp_option>` name/value pairs parsed from an attacker-supplied WXR import file to be passed directly to `update_option()`. This makes it possible for authenticated attackers, with Shop Manager-level access and above, to write arbitrary WordPress options — most critically setting `users_can_register` to `1` and `default_role` to `administrator` — enabling open self-registration of Administrator accounts and full site takeover. This is exploitable by Shop Manager-level users because WooCommerce grants that role the `import` capability, allowing it to reach the WordPress Importer flow that fires the `import_start` hook on which `rum_importer()` is registered, contrary to the assumption that the hook is restricted to Administrators.

The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor.

An attacker operating through a network path may attempt exploitation with elevated privileges. If successful, the issue may gain additional privileges.
