ShopEngine vulnerabilities

The ShopEngine Elementor WooCommerce Builder Addon – All in One WooCommerce Solution with eCommerce Templates & Woo Widgets plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘shopengine_product_title_header_size’ parameter in all versions up to, and including, 4.9.5 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Author-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

The ShopEngine plugin for WordPress is vulnerable to privilege escalation in all versions up to and including 4.9.4. The `rum_importer()` function is registered on the `import_start` hook without proper capability checks, allowing authenticated attackers with Shop Manager-level access to write arbitrary WordPress options, including setting `users_can_register` to 1 and `default_role` to administrator, enabling open self-registration of Administrator accounts and full site takeover.

The ShopEngine Elementor WooCommerce Builder Addon plugin for WordPress up to version 4.8.4 is vulnerable to unauthorized data modification due to insufficient capability checks in the post_deactive() and post_activate() functions. This allows authenticated attackers with Editor-level access or above to activate and deactivate licenses.
