The YITH Essential Kit for WooCommerce #1 plugin for WordPress has a security issue that allows unauthorized changes to be made to its data. This is because the plugin does not have a check in place to ensure that only authorized users can activate, deactivate, or install modules. This vulnerability exists in all versions of the plugin up to 2.34.0, which means that attackers with Subscriber-level access or higher can manipulate the plugin by installing, activating, or deactivating certain YITH plugins.
